Chapter 1: Introduction

Matrox Pulsar
M atrox Pulsar is a single-slot PCI frame grabber that features on-board acquisition, display capabilities, and real-time transfers to Host memory. It features a 2 Mbyte image frame buffer and a 2 Mbyte graphics overlay (VGA ) frame buffer for non-destructive overlay capabilities. You can program Matrox Pulsar using the Matrox Imaging Library (M IL) or any of its derivatives. A low-cost version of Matrox Pulsar is also available: Matrox Pulsar-LC. Matrox Pulsar-LC does not include the display section. In general, this manual does not explicitly refer to the M atrox Pulsar-LC because any discussion of M atrox Pulsar also applies to Matrox Pulsar-LC (except discussion of the display section).

Acquisition features
Matrox Pulsar is a monochrome frame grabber that has standard (R S-170/CCIR) and non-standard acquisition capabilities (for example, high resolution or digital video sources). It is capable of 8-bit digitization at up to 45 MHz or 10-bit digitization at up to 30 MHz. Using an optional RS-422 digital-interface companion board, Matrox Pulsar can acquire 16-bit digital data at speeds of up to 30 MHz. To interface and switch between multiple video sources, Matrox Pulsar features four analog software-selectable input channels and a 16-bit wide digital interface.

Display features
The display section is powered by the Matrox MGA-2064W graphics accelerator that can display at resolutions up to 1600x1200x256 colors with refresh rates of up to 85 Hz. This graphics accelerator can be used as the Host's main display controller, eliminating the need for a separate display board. Alternatively, it can be used with a separate graphics board so that you can work in dual-screen mode. The overlay (VGA) and main frame buffers support common zooming (by factors of 2 or 4), panning, and scrolling.

PCI bus inter face
Matrox Pulsar's high-speed, 32-bit PCI bus interface supports transfers of 132 M bytes/sec (peak transfer rate for a bus running at 33 MHz), providing real-time transfer of images to on-board display memory or directly to Host memory.

y Some older PCI buses run at 30 MHz, which implies a
120-M Hz peak transfer rate.

Chapter 1: Introduction

Software
You can purchase one or more of the Matrox Imaging software packages that support the M atrox Pulsar board. These are MIL and its derivatives (MIL-Lite, ActiveMIL-Lite, and Inspector). MIL M IL is a developm ent library with commands for image acquisition, transfer, display control, and image processing applications. Environments supported are Windows 95, Windows NT 4.0, and DOS4GW 32-bit DOS extender. M IL provides an extensive list of commands for image processing, geometric transformations, pattern matching and alignment, measurement, blob analysis, and optical character recognition. MIL-Lite M IL-Lite is a subset of M IL. It includes all the MIL commands for image acquisition, transfer, and display control. ActiveM IL is a set of ActiveX controls that are based on MIL. ActiveM IL was designed for rapid application development (RAD) tools, such as Microsoft's Visual Basic. Environments supported are Windows 95 and Windows NT 4.0. Inspector is an interactive Windows application for image capture, processing, analysis, and archiving. Environments supported are Windows 95 and Windows NT 4.0. Developers can use Matrox Inspector as a prototyping tool to quickly build proof-of-concept dem onstrations for their machine vision, image analysis, and medical imaging system. Intellicam M atrox Intellicam is an interactive Windows program that allows fast camera interfacing and provides interactive access to all the acquisition features of your Matrox Pulsar board. M atrox Intellicam also has the ability to create a digitizer configura tion format (DCF) file, which MIL and its derivatives use to interface to specific non-standard video sources. Intellicam is included with both MIL and MIL-Lite. Environments supported are Windows 95 and Windows NT 4.0.

What you need to get started
To begin using Matrox Pulsar, you need the following:
s s

PC with a PCI bus and a Pentium processor or better. When running Windows 95, 16 M bytes of memory are required; when running Windows NT 4.0, 24 Mbytes of memory are required; when running DOS4GW, 4 Mbytes of memory are required. These are minimum requirements. For full Matrox that use newer 430VX, 430TX, offer the requir Pulsar functionality, we recommend systems PCI chipsets, such as the Intel 430HX, 440FX, and 440LX, because they generally ed sustained-throughput capability.

s

v Important

s

Your PCI system's BIOS must be able to properly configure a PCI-to-PCI bridge chip and correctly initialize the VGA residing on the secondary PCI bus. A list of PC platforms compatible with Matrox Pulsar can be found on the Matrox Imaging Web site. If you are using a system that is different from those on the tested systems list, ask your PC manufacturer if your software meets the listed requirements. A PC with an empty, full-length 32-bit PCI expansion slot (bus master capable). A second slot (ISA) is required if you plan to install the optional RS-422 digital-interface companion board. A CD drive, and a hard disk or network drive on which to install the Matrox Pulsar software.

Chapter 1: Introduction

Installation overview
The installation procedure consists of the following steps: 1. Complete the hardware installation as described in Chapter 2. If you have any problems, consult Appendix A. 2. Complete the software installation as described in Chapter 3. More infor m ation For information on the Matrox MGA software, see Chapter 4. For information on using multiple Matrox Pulsar boards, see Chapter 5. For information on the Matrox Pulsar hardware, see Chapter 6. If you want more technical information about Matrox Pulsar, including specifications and connector pinout descriptions, see Appendix B. Conve ntions When the term Host is used in this manual, it refers to your PC. This manual occasionally makes reference to a MIL-Lite command. However, anything that can be accomplished with M IL-Lite can also be accomplished with MIL, ActiveMIL-Lite, or Inspector.1 Need help? Appendix A offers solutions to potential problems. If your M atrox Pulsar installation questions are not answered in this manual, contact your local M atrox representative, M atrox sales, or Matrox customer support (see the Customer Support section at the back of this manual). In the unlikely event of a failure, the warranty and Product Assistance Request Form at the back of this manual outline return conditions and procedures.

1. Most items can be accomplished with Inspector.

Chapter 2: Hardware installation

Installing Matrox Pulsar
Before you install your board, some precautionary m easures must be taken. Turn off the power to your computer and peripherals, and drain static electricity from your body (by touching a metal part of the computer chassis). Next, proceed with the following steps to install your board. Steps for installation 1. Remove the cover from your computer using the instructions from your computer manual. 2. If you wish to use M atrox Pulsar as the main display controller, remove or disable any existing VGA board in your system. For more details, see Choosing your display configuration later in this chapter. 3. Check that you have an empty PCI (32-bit) accomodate a full length board. If you do not slot, remove a PCI board from your system for Matrox Pulsar and take note of the slot choose.

slot that can have an empty to make room number you

ISA CARD SLOTS

v Caution

Some computers have a large, black-ridged heat sink that prevents long boards from using most PCI board slots. Matrox Pulsar must not touch this heat sink. Therefore, choose a slot where the board completely avoids it. For digital input, you must free up a second slot. If you are installing the optional R S-422 digital-interface companion board, this slot must be an ISA slot. 4. If present, remove the blank metal plate located at the back of the selected slot. Keep the screw at the top since you will need it to fasten the Matrox Pulsar board.


Installing Matrox Pulsar

5. Before you install your board, ensure that the DIP switches are set properly for the display configuration you want to use. The default settings, which are for a single-screen configuration, are shown in the illustration below:

See the next section for more details on setting these switches. 6. Carefully position M atrox Pulsar over the selected PCI slot, as illustrated below.

Note that Matrox Pulsar has a PCI board retainer attached to it. This is because most systems have both PCI and wider slots (for example, ISA slots). In these systems, the smaller PCI board needs a retainer to make it long enough to slide between the guides and hold it firmly in place. If you have a PC where all the slots are PCI slots, simply unscrew the PCI board retainer from the Matrox Pulsar board. 7. Slide the board into the slot. Ensure that the attached PCI board retainer slides between the guides, and that Matrox Pulsar 's bracket, at the back of the board, slips into the PC's chassis.


18

Chapter 2: Hardware installation

8. Once the board is perfectly aligned, press it firmly but carefully into the slot's connector. 9. Anchor the board by replacing the screw that you removed. 10. If you have to install the optional RS-422 digital-interface companion board: a. Connect one of the flat ribbon's connectors to the 50-pin m ale connector on the RS-422 digital-interface companion board. You must connect these two connectors so that the triangular etchings on the connectors are facing each other. The triangular etchings indicate pin 1 and the location for pin 1, respectively.

b. Repeat steps 6 through 9 to install the board in your PC. This time, however, install the board in the selected ISA slot. Note that the retainer is not required because the board is much shorter.

c. Connect the other end of the flat ribbon cable to Matrox Pulsar's 50-pin digital-interface connector. Again, match the triangular etchings.


Installing Matrox Pulsar

12. If you have to install the optional PLS-TTL-CABLE flat ribbon cable to receive/send digital RS-422/TTL control signals:

a. Connect the 50-pin female connector of the ribbon cable to the 50-pin digital interface connector of the Matrox Pulsar board. You must connect these two connectors so that the triangular etchings on the connectors are facing each other. The triangular etchings indicate pin 1 and the location for pin 1, respectively. b. Replace the bracket that you removed from the selected empty slot with the bracket attached to the other end of the ribb on cable. Anchor the bracket with the screw. 13. Attach your monitor(s) and input sources. For details, see the Connecting external devices section. 14. Turn on your computer. Under Windows 95, when you boot your PC, Windows' Plug-and-Play system will detect a new PCI Multimedia Device and you will be asked to assign it a driver. At this point you should click on Cancel.
y

Note that when you select Cancel in older versions of Windows 95, Windows 95 will log the device as unidentified. Since you cannot run MIL-Lite while Windows detects an unidentified device, run the System utility from the Control Panel, select the Device Manager property sheet, and under the Other Devices option, remove "PCI Multimedia Video Device". Now, you can install MIL-Lite. If MIL-Lite was already installed, you need to uninstall and reinstall it.

Chapter 2: Hardware installation

Choosing your display configuration
M atrox Pulsar can be used as the VGA for your system. If you have a built-in VGA on your motherboard and it is active, your system's BIOS will automatically disable it when Matrox Pulsar has its DIP switch 2 set to off. If you want to use Matrox Pulsar as your VGA for single screen or multi-head mode, set DIP switch 2 to off. Any VGAs that are not being used in these modes should be disabled.

To use Matrox Pulsar in dual-screen mode, disable Matrox Pulsar 's VGA by setting DIP switch 2 to on.


Connecting external devices

21

Connecting external devices
Matrox Pulsar has three connectors, of which two are located on its bracket. The optional RS-422 digital-interface companion board has a 68-pin connector, while the digital interface ribbon cable (PLS-TTL-CABLE) has a DB-37 connector.

The connectors on Matrox Pulsar itself are as follows:
s

A 15-pin VGA video output connector (DB-15) that sends analog video and digital synchronization signals to the monitor. Digital interface connector. A 50-pin digital interface connector to which you can attach the optional RS-422 digital-interface companion board (using a flat ribbon cable) or an external digital interface ribbon cable.

s

s

The connectors on the RS-422 digital-interface companion board are as follows:
s s

A high-density, SCSI-2, D-shell, 68-pin receptacle. A 50-pin male digital video input connector.
y

Refer to Appendix B for a more detailed description of these connectors.


22

Chapter 2: Hardware installation

Connecting to a monitor
M atrox Pulsar works with VGA and high-resolution monitors. Use the video cable supplied with your monitor to connect it to the video output of Matrox Pulsar. The steps to attach your monitor to your Matrox Pulsar board are as follows: 1. If your monitor has input impedance switches, set the switches for the red, green, and blue inputs to 75 ohms, as shown in the illustration below. Set the switches for the synchronization inputs according to your monitor's manual. In most cases, these switches should be set to high impedance and external sync mode.

2. Connect the display monitor to Matrox Pulsar's 15-pin female video-output connector (DB-15). If your monitor has a DB-15 connector, use the standard DB-15 to DB-15 cable that is usually provided with your monitor. If your monitor has 5 B NC -type connectors, use a DB-15 to 5 BNC cable.

Attaching a video source
Analog video source Matrox Pulsar supports a wide variety of analog video sources. Interfacing to these video sources is possible through the video input connector. There are two optional cables with which you can attach an analog video source:
s

The IMG-7W2-TO-5BNC cable connects to the video input connector. It has five BNC connectors and a female connector, with 2 coaxial receptacles and five contacts. The cable's electric wires are color-coded. This cable allows you to attach up to four analog video sources and a trigger input, as follows:
ê ê ê ê ê

RED wire - Analog video input 1 GREEN wire - Analog video input 2 BLUE wire - Analog video input 3 BLA CK wire - Analog video input 4 YELLOW wire - TTL Trigger input

s

The IMG-7W2-TO-1BNC cable connects to the video input connector. It has one BNC connector (CHANNEL 1) and a female connector, with 2 coaxial receptacles and five contacts.

Digital video source

To acquire digital data, use the PLS/CBL/OPEN cable to attach the RS-422 digital-interface companion board to your video source. Attach the high-density, SCSI-2, D-shell, 68-pin plug of the cable to the RS-422 digital-interface companion board's 68-pin receptacle.

No circuitry protection
v Warning
The trigger signal on M atrox Pulsar is not buffered or conditioned. The circuits on M atrox Pulsar are sensitive to static electricity and surges. Be careful about what is hooked up to the board since there is no circuitry protection. There are different ways to provide some protection. For example, you can add an opto coupler to your TTL trigger source. This would help isolate the rest of the circuitry from surges.

The display section of Matrox Pulsar is powered by the Matrox M GA 2064W (used on MGA Millennium) graphics accelerator. As a result, the MGA PowerDesk works with Matrox Pulsar. The MGA PowerDesk is installed when you install the MGA WIN NT or MGA WIN 95 display driver. Installation of these display drivers was discussed in Chapter 3. Driver version If you have a different version of the M GA PowerDesk, some information m ight be different; for the most up-to-date information, refer to the on-line help of the MGA PowerDesk. The MGA PowerDesk group includes the following programs:

Desktop features
The MGA PowerDesk includes several desktop features:
s s s s s s s s

CenterWINDOW C enterPOPUP M axVIEW PanEND PanHOME PanLOCK Zoom (PixelTOUCH) A cceleration features

You can access these features by pressing the Advanced button from the MGA Settings property sheet, then using the MGA PowerDesk property sheet from the presented dialog box.

CenterWINDOW
CenterWINDOW pans and scrolls the desktop to center the active display window on the screen. This is useful when you have opened multiple applications and they are not all visible at once on your desktop. With CenterWINDOW, you can center the display around any one of them. To center the display of the active application, switch to the desired application using Task M anager (Ctrl+Esc) and then use the CenterWINDOW hot key. The mouse pointer is positioned in the center of the window. Note that, in a multi-head configuration, repeatedly pressing the C enterWINDOW hot key will cause the currently active window to be centered on one screen, then on the next, then on the other, etc.


Desktop features

35

CenterPOPUP
CenterPOPUP ensures that every pop-up error message or warning dialog box appears centered on the screen. This is very useful when you are using a virtual or zoomed desktop. This feature works only on pop-up windows, which means that other types of windows (such as application windows, floating toolbars, etc.) are not affected. CenterPOPUP differs from CenterWINDOW in one essential way: CenterPOPUP moves the pop-up window into the desktop area that is displayed on the screen, whereas CenterWINDOW pans and scrolls the desktop to center the active application window on the screen.

MaxVIEW
MaxVIEW limits the size of the window so that it does not extend outside your immediate on-screen work area (you can still scroll to any off-screen area on your desktop). When enabled, M axVIEW applies to any Windows application that is maximized.

y Some programs, such as MS Word for Windows, might extend
vertically beyond the visible window, even when MaxVIEW is enabled.

PanEND
PanEND moves your display to the bottom of a vertical virtual desktop or to the right of a horizontal virtual desktop. This feature is for a virtual desktop only.

PanHOME
PanHOME moves your display to the top of a vertical virtual desktop or to the left of a horizontal virtual desktop. This feature is for a virtual desktop only.

PanLOCK
PanLOCK enables or disables panning. When enabled, you can move your mouse pointer to the edge of the view area to pan in that direction. This feature can be used if you have a virtual or zoomed desktop.

Chapter 4: MGA PowerDesk

Zoom (PixelTOUCH)
Zoom uses the MGA hardware to instantly zoom your desktop by a factor of 2 or 4. When zooming, you are working with a pseudo-virtual desktop. Moving the cursor to the different edges of the screen will pan your display to different portions of the Windows desktop. You can change the zoom factor by:
s

Using the Zoom buttons in the MGA Control Panel dialog box; or Using the PixelTOUCH hot key. The PixelTOUCH hot key, when enabled, toggles in a circular order through the three zoom factors (x1, x2, x4, x1, ...); or Using QuickDesk. To zoom in or out of the current view, click on the ` +' or ` -' button, respectively.

s

s

Note the following:
s

The x4 zoom is not available at resolutions of 800 x 600 and lower. The display pans 32, 64, and 128 pixels at a time at zoom factors of x1, x2, and x4, respectively. The PixelTOUCH hot key does not work in a DOS shell.

s

Acceleration features
The Device Bitm aps option, when enabled, stores bitmaps in M atrox Pulsar's overlay (VGA) frame buffer (off-screen) instead of the RAM on your PC (Host RAM ).

y The Device Bitmaps option has been proven to improve
performance when used with some applications. However, with certain applications, the display is redrawn incorrectly if this option is enabled. If this happens, disable the option when using that application.

Chapter 5: Using multiple Matrox Pulsar boards

Using multiple Matrox Pulsar boards
This section describes how multiple Matrox Pulsars can be supported in a single PC. Using multiple M atrox Pulsar boards, you can grab multiple images simultaneously and display the images on the respective boards. It is possible to grab from genlocked cameras or from non-synchronous sources (in the latter case, camera outputs can be different). When the Matrox Pu display, the display o be live or pseudo-live and the available PC lsar boards are used in a multi-head f grabbed images from each camera will depending on the position of the windows I bandwidth.

Multiple board installation
Install each additional M atrox Pulsar board in the same way you installed the first (refer to Chapter 2). In other words, place each additional board in an empty PC I slot, taking care that they avoid the CPU heat sink. You can theoretically have as many as 16 Matrox Pulsar boards installed in your PC at one time; this number is, however, limited by the number of empty slots in your PC and, for simultaneous grabs, by the available PCI bandwidth of your PC. If you want to use Matrox Pulsar boards in a multi-head display, their VGA must be enabled (their DIP switch 2 must be off). For more information about selecting your display mode, refer to Chapter 2.

The number of boards from which you can simultaneously grab is determined by the available PCI bandwidth of your PC. This is discussed later in the chapter.

42

Chapter 5: Using multiple Matrox Pulsar boards

Number of cameras per board
M atrox Pulsar has four software-selectable video input channels, but only one analog-to-digital converter. Therefore, although you can connect up to four cameras per board, you can only grab from one monochrome camera at a time.

PCI bandwidth requirements
Sustained PCI-transfers to memory require the use of a high performance PCI core-logic chipset, such as the Intel 430HX, 430VX, 430TX, 440FX, or 440LX. If a high performance chipset is used, you should not have any PC I bandwidth problems when transferring two full-sized images simultaneously from two M atrox Pulsar boards in real-time. However, transferring more than two images simultaneously might result in PCI bandwidth problems. When transferring images from three or more Matrox Pulsar boards simultaneously, you will have to reduce the image size to avoid reaching the upper limits of the overall available bandwidth.

Matrox Pulsar hardware reference
This chapter provides information on the architecture of the M atrox Pulsar hardware, as well as the features and modes available with the board. It also indicates how to control these various features and modes. The chapter is divided into three sections: the first section describes the Matrox Pulsar hardware that is associated with the acquisition of images. The second section describes the hardware related to the display of images. The third section discusses the data interface, and how to transfer grabbed images to on-board memory and Host memory. A summary of the information given in this chapter and a detailed description of the pinouts and connectors is available in Appendix B .

To set up the grab section, check if there is a supplied DCF file that matches your video source type. The M IL-Lite command MdigAlloc() uses this DCF file to define how to accept or generate video timing signals (for example, the horizontal sync, vertical sync, and pixel clock) and the video signal format (for example, in the case of digital video, TTL or RS-422). If you find a DCF file that is appropriate for your video source, but need to adjust some of the more common parameters, you can do so directly, without adjusting the file, using the Mdig...() commands of M IL-Lite. For more specialized adjustments, you can adjust the file itself, using M atrox Intellicam. If you cannot find an appropriate DCF file, you can create your own, also using Matrox Intellicam. For more information on Matrox Intellicam, refer to the Matrox Intellicam User Guide.

Synchronization
Matrox Pulsar can operate in either slave or master mode. Slave mode
s

In slave mode, the video source provides the synchronization information to M atrox Pulsar. It can accept one of the following synchronization schemes:
ê

Synchronization signals are encoded on the analog video signal provided to the board. Horizontal and/or vertical synchronization signals are supplied separately by the video source in either TTL or RS-422 standard. The video source provides a composite synchronization signal in either TTL or RS-422 standard.

ê

ê

Master mode

s

In master mode, M atrox Pulsar generates the horizontal and/or vertical synchronization signals and supplies them to the video source. In this case, the video source must synchronize to the board.


46

Chapter 6: Matrox Pulsar hardware reference

Trigger

M atrox Pulsar accepts an external trigger input which allows image acquisition to be synchronized to external events. The board accepts either a TTL or an RS-422 external trigger signal. The TTL level signal must have a maximum amplitude of 5 V. A signal over 2 V is considered high, while anything less than 0.8 V is considered low. The transition of 0.8 V to 2 V is considered to be the rising edge. The trigger signal's pulse width must be greater than one pixel. You can determine the pulse width by taking the inverse of the pixel frequency. For example, if the pixel frequency is 12.27 MHz, the pulse width is 1/12.27 MHz 82 nanoseconds.

v Warning

The trigger signal on M atrox Pulsar is not buffered or conditioned. The circuits on M atrox Pulsar are sensitive to static electricity and surges. Be careful about what is hooked up to the board since there is no circuit protection. There are different ways to provide some protection. For example, you can add an opto-coupler to your TTL trigger source. This would help isolate the rest of the circuitry from surges.

Exposure

M atrox Pulsar also has two software and hardware re-triggerable timers whose outputs drive the EXPOSURE signals of the 50-pin digital connector. These timers allow you to control the video source exposure time or other related external events. The controls for the trigger, timers, and all video source settings are configured in the DCF file; however, you can change the trigger mode, exposure time, input-signal gain, and LUT palette, using the MIL-Lite command MdigControl().


Acquisition section

The phase-locked loop
The high-performance, low-jitter phase-locked loop (PLL) uses frequency synthesis techniques to generate the clock signal, when necessary. The PLL can use the following sources as a reference:
s s

The on-board crystal oscillator. The horizontal video synchronization signal supplied by the video source (line-locked mode). The clock signal supplied by the video source (to generate a different clock).

s

When in line-locked mode and accepting a composite video signal, the PLL can synchronize to either serrated or block vertical synchronization signals. Operating frequency range Jitter 5 to 45 MHz ± 2 ns (when using a stable reference)

When the input source supplies a sampling clock that is not used to generate a different clock, the PLL is bypassed to avoid adding jitter to the supplied clock.


48

Chapter 6: Matrox Pulsar hardware reference

The programmable synchronization generator
The programmable synchronization generator (PSG) has various functions related to video synchronization and control:
s

It to or sa

supplies a feedback signal to the PLL, allowing it to lock such signals as the input video source, a reference signal, an external clock. The PSG is then fully responsible for the mpling clock value.

s

It supplies the control signals to the video-to-PCI bridge, thereby determining the active video region and providing the possibility of sub-sampling it. Sub-sampling factors Horizontal Vertical 1 1 2 1 2 2 4 4

s

It provides support for standard interlaced and non-interlaced video. It supports many (if not all) non-standard video types, through the use of the PSG trigger, and the horizontal and vertical reset inputs. The PSG trigger input is used to activate non-standard scan modes. The reset inputs allow the PSG to synchronize to external events. By appropriately selecting the reset and PSG-trigger sources, and setting the proper mode of operation, the PSG allows M atrox Pulsar to adapt to virtually any video standard.

s

Using Matrox Intellicam, you can set the active video region, the sampling clock, and all the other parameters related to the timing of the video signal (that is, standard and non-standard video, interlaced or non-interlaced) in your DCF file. Once this is done, some of the video parameters, such as the sub-sampling factor, can be changed, using the MIL-Lite com mand M digControl().


Acquisition section

49

Analog input
The analog input section includes the electronic components needed to select, amplify, filter, and drive the video signal prior to sending it to the analog-to-digital converter (A/D converter). Matrox Pulsar has 4 analog software-selectable input channels to switch between multiple video sources. These can be controlled using the MIL-Lite command M digC hannel(). In addition, you can change the amplification gain using the MIL-Lite command M digControl(). This means you can optimize the video input signal such that the full dynamic range of the 10-bit A/D converter is used. The supported gain factors are as follows: Input video signal amplitude (excluding sync) 1.5 to 2.0 V 1.0 to 1.5 V 0.7 to 1.0 V 0.5 to 0.7 V 0.0 to 0.5 V Total input video signal amplitude (including sync 2.14 to 2.86 V 1.43 to 2.14 V 1.0 to 1.43 V 0.71 to 1.0 V 0.0 to 0.71 V

Required ) gain setting 0.35 0.47 0.70 0.98 0.28

MIL
M_GAIN0 M_GAIN1 M_GAIN2 M_GAIN3 M_GAIN4

The input low-pass filtering stage is used to limit high frequency noise and to limit aliasing effects at the input of the A/D converter. Because the sampling frequency can vary greatly from one application to another, Matrox Pulsar offers two cutoff frequencies between which you can choose when configuring your DCF file. These are:
s s

10 M Hz 21 M Hz

After the filtering stage comes the DC restoration circuitry, followed by a wideband, low-distortion video driver.


50

Chapter 6: Matrox Pulsar hardware reference

10-bit A/D converter and reference levels
M atrox Pulsar uses a high-quality, high-speed, 10-bit analog-to-digital converter to sample the video signal. This allows Matrox Pulsar to offer excellent digitization quality, even at the highest sampling frequency. The A/D converter also features a wideband input section, allowing full use of its sampling speed. The black and white reference levels can be set individually. Each reference level can be adjusted in increments of approximately 5mV and has 256 steps. Since the video signal is AC coupled, a DC restore circuit is required to adjust the black reference level. This clamping circuit is composed of a switch that charges a capacitor to the black level during the horizontal back porch of the video signal. The capacitor keeps its charge for the length of the video line, and will be readjusted on the next line. The signal-to-noise ratio (SNR) of the A/D is 56 dB for a signal at up to 10 MHz. This corresponds to 8.8 effective bits (ENOB). For applications where a higher pixel resolution must be obtained on a specific voltage range of the input signal, use the M IL-Lite command M digReference() to set the black and white reference levels.


Acquisition section

51

Lookup table (LUT)
Matrox Pulsar has a programmable input lookup table that can transform greater than 8 bits per pixel data to per pixel for transfer to the display section or the Host. also be used to simply remap an incoming video data st (LUT) 8 bits It can ream.

The m aximum size of the LUT is 8K entries by 16 bits, allowing up to 13-bits true LUT mapping. For 14- to 16-bit digital input signals, the input LUT is used as two 256x8-bit LUTs (one for the high byte, one for the low byte) to produce a 16-bit output.

Video-to-PCI bridge
The video-to-PCI bridge is a router that sends data to the on-board frame buffers, to Host memory, or to off-board devices (for example, V GA display buffers). When transferring 8- or 16-bit data, the video-to-PCI bridge packs the pixels together and performs burst transfers, acting as a bus master on the PCI bus. This allows optimal use of the available PCI bandwidth and frees the CPU to perform other tasks. The video-to-PCI bridge can also generate various interrupts towards the Host processor. These interrupts are:
s

Grab events: grab-end, grab-frame-end, grab-field-end, grab-field-end-odd, and grab-field-end-even. Video synchronization events: field-start, field-start-odd, and field-start-even.

Matrox MGA-2064W graphics accelerator
The display section is powered by the 64-bit M atrox MGA-2064W graphics accelerator. It interfaces directly with the on-board secondary PCI bus. The Matrox MGA-2064W graphics accelerator doubles the bandwidth available for data to travel from the graphics engine to the video memory. By doubling the bandwidth, the MGA-2064W is able to process twice as much information as 32-bit graphics accelerators. This translates into higher refresh rates and frees up the CPU.

Image and overlay frame buf fers
The display section has a total of 4 Mbytes of frame buffer memory connected directly to the M GA-2064W: 2 Mbytes for the image frame buffer (8-bit monochrome) and an additional 2 M bytes for the overlay (VGA) frame buffer (8-bit pseudo color). The frame buffer's dual-ported design allows it to accept data from the accelerator and refresh the screen simultaneously, increasing speed and performance. You can overlay text and 8-bit pseudo-color graphics on the main image frame buffer using a specified color key. The key color can be set using the M IL-Lite command MdispOverlayKey(). To configure the overlay frame buffer to the desired resolution, use the MGA PowerDesk (see Chapter 4). The image frame buffer automatically uses the same resolution. If you are not using Matrox Pulsar as the main VGA, set the resolution of the Matrox Pulsar display using the MIL-Lite command MdispAlloc(). You can move around images larger than the display resolution using pan and scroll operations. In addition, you can zoom in on images by a factor of 2 or 4. Zoom, pan, and scroll operations are only display effects and do not modify the data in the frame buffers. Note that zoom, pan, and scroll operations affect both the image and overlay frame buffers.

Chapter 6: Matrox Pulsar hardware reference

The RAMDAC
A 128-bit RA MDAC provides digital-to-analog conversion. It supports the display of captured video in real-time at a maximum resolution of 1600x1200 with a 85-Hz non-interlaced refresh rate. The RAMDAC has three 8-bit LUTs that map the contents of the overlay frame buffer.


The data interface section

55

The data inter face section
Matrox Pulsar uses the PCI bus. The PCI bus uses a 5 V signaling environment and has a 32-bit data bus. It is capable of a 132 Mbytes/sec peak transfer rate. The following is an illustration of the data interface section.

PCI-to-PCI bridge
The PCI-to-PC I bridge isolates traffic between devices on the primary (Host) PCI bus and the secondary (on-board) PCI bus. Therefore, transfers to the on-board frame buffer occur independently of the Host, without affecting its performance. The maximum peak data transfer rate of the secondary PC I bus is also 132 M bytes/sec.


56

Chapter 6: Matrox Pulsar hardware reference

Data transfer rate
Although the PCI's maximum data transfer rate is 132 M bytes/sec, actual performance is generally much less; it depends on CPU memory caching, interactions between boards, and the quality of the system's PCI bus interface. Some PCI bus systems, for example, those with an Intel 430NX (Neptune) chipset, do not offer sufficient bandwidth for full transfer capability with Matrox Pulsar. PCI bus systems using a newer PCI chipset, such as the Intel 430HX, 430V X, 430TX, 440FX, or 440LX, offer sufficient bandwidth to ensure full transfer capability to system memory with M atrox Pulsar. In such cases, Matrox Pulsar can achieve the following data rates: Initiator (Master) Host memory Matrox Pulsar Access Type Location write write Performance

frame buffer 50 M bytes/sec Host memory 60 M bytes/sec

Installation problems
My system hangs during installation of the MGA Windows 95 PowerDesk. Your system might hang during installation of the M GA Windows 95 PowerDesk if your win.ini file is unusually large or DOS memory is low. This is because the installation program runs only within DOS memory and reads this file entirely into memory. You might have to t during installation is the case, contact instructions before emporarily reduce the size of the win.ini file of the MGA Windows 95 PowerDesk. If this the Imaging Customer Support Group for you proceed.

After installing the MGA Windows NT 4.0 driver for my Matrox Pulsar, my system does not reboot at the expected resolution. This is a problem that you are likely to encounter if the resolution settings are incorrect or if the MGA display driver is not the correct version. These problems can be addressed in the following ways:
s

To verify the current resolution settings or to change them, click on the MGA QuickDesk icon (generally located at the bottom right of your monitor) and select Display Properties. The Display Properties dialog box appears. Select the MGA Settings property page. Set the resolution to one that is supported by your monitor and click on Apply. Install the M GA display driver provided with the Matrox Pulsar software.

s



Device attached to the PC fails to start under Window s NT 4.0. This is a type of message that you will receive if a device failed to start. Your PC will prompt you to go to the Event Viewer to identify the device that was unable to start. This could happen due to the following two reasons:
s

The drivers are not installed correctly. This problem could occur due to too much or insufficient allocation of DMA memory. This problem can be addressed by uninstalling and reinstalling the drivers that failed to start, and by specifying the correct DM A setting. There is a conflict in the BIOS Setup program. This problem generally occurs when there is a PCI m emory mapping error or when there is a PCI-IRQ routing error. This problem could be resolved by first trying to swap boards from one PCI slot to another. If the problem still persists, upgrade your BIOS.

Appendix A: Troubleshooting

Grabbing problems
While grabbing, my Matrox Pulsar board stalled. Grab operations make use of the interrupt line assigned to the PCI slot where the board is installed. These operations might freeze or not function properly for the following reasons:
s

There is no interrupt line assigned to the PCI slot where the board is installed; The interrupt line used by the board is shared by the PCI bus and another bus (ISA or EISA); The interrupt line used by the board is shared with another PCI device (e.g. network board, SCSI board, etc.).

s

s

M ake sure that an interrupt line (IRQ) has been assigned to your Matrox Pulsar's PCI slot. To do this, check your system setup or use one of the external utilities that came with your PC. Your computer manual might also be of help.

y PCI devices cannot share common interrupt lines with EISA
or ISA devices. However, PCI devices can share an interrupt line. Shareable interrupt lines With the PCI bus, interrupt lines are shareable among PCI devices. However, the PCI bus must not use any interrupt lines that are also used by the ISA or EISA bus. If you cannot assign an interrupt line that will be used exclusively by M atrox Pulsar, try to assign an interrupt line that Matrox Pulsar can share with another PCI device. If problems still occur, try sharing a different interrupt line. Disabling interrupts To determine if there is a conflict with the assigned interrupts, you can temporarily disable the use of interrupts. To do so, pass the appropriate initialization flag to the MsysAlloc() command when allocating the Pulsar system. For more information, refer to the M atrox Pulsar-specific description of M sysAlloc() in the M IL B oard-specific Notes or in the appropriate appendix of the M IL-Lite User Guide, Command Reference, and Board-specific Notes. Note that, by disabling interrupts, you will run with limited grab functionality.


Troubleshooting

I cannot grab or I grab incomplete frames (or fields). Grabbing might not be possible or might be incomplete (grabs only a few lines) if your system does not have sufficient Host memory or PCI-bus bandwidth. Some currently available PCI bus systems do not offer sufficient bandwidth for full-transfer capability to Host memory with M atrox Pulsar.

Limited memory availability
I get an error message stating that there is insufficient DMA memory. With some DPMI servers under DOS, the amount of Host DMA memory external to M atrox Pulsar and usable by this board for grab operations is limited. Under Windows, this limit is approximately 8000 KBytes, but varies depending on the configuration of the system. Not enough m em ory to allocate buffer under Window s NT 4.0. This is a message that you will receive if you allocate a grab buffer that is greater than the amount of DM A memory specified at the time of software installation. This problem can be addressed by allocating more memory. To do so, type the following line at the Windows' run prompt:
mildrv pulsar x replace

Repla ce KBytes. Window only hal

x with the appropriate amount of DMA m emory in Note that for every x amount of DMA memory required, s NT reserves twice that amount as non-paged memory, f of which is accessible to the user.

PCI system incompatibility
Matrox Pulsar doesn't work on my PCI-bus system. Some currently available PCI system s do not recognize PCI-to-PCI bridges due to limitations in their B IOS software. Consequently, the system will not boot since it cannot initialize the display controller.

Appendix A: Troubleshooting

Booting problems
My computer beeps, hangs shortly after booting, or will not boot when I turn on the power. There are many possible causes for such a problem. Don't be alarmed; these problems are often temporary and require quite simple solutions. Check the following:
s

E nsure that DIP switch 1 is in its default position (refer to C hapter 2). R emove any non-compatible display adapters (such as an E GA or V GA) from your system, and ensure that the motherboard's VGA is disabled. C heck for a register (input/output) conflict. Conflicts are not very likely since M atrox Pulsar resides in the standard VGA register space and occupies another fully configurable memory space that the system can change during bootup.

s

Register conflicts

s

Video Display Problems
My monitor is blank (or it has shades or spots of gray and white).
s

C heck that the system is plugged in and make sure your computer and monitor are turned on. R echeck your connections at both ends of the video cable. E nsure that Matrox Pulsar is sitting evenly and is fully inserted into its slot. To do this, press the board down firmly. C heck that the brightness and contrast controls are set correctly. Set the monitor's swit (RGB) inputs, and set to high-impedance if t Digital/A nalog switch ches (if any) to 75 ohms for the video the synchronization to ` external' (and his option is available). If there is a on your monitor, set it to Analog. or th ur or register conflict (see Booting e documentation for all other system and check that they are register space used by Matrox

The colors are wrong. Incorrect colors indicate that either the cabling (for monitors that don't have a built-in cable) or monitor impedance is incorrect.
s

Ensure that the red, green, and blue lines are connected to the corresponding red, green, and blue m onitor inputs (some monitor input connectors are not in the expected order). Make sure your monitor's RGB inputs are set to 75 ohm s. Several monitors have individual switches to set the impedance of the inputs. Make sure that they are all set to 75 ohms. On some PCs, you must run a setup program or set DIP switches to select the main video adapter type. For most PCs, you should select an EGA/VGA type. R efer to the user manual of your computer. Check the cable continuity.

The display is not centered. Adjust the centering control of your monitor to position the picture on the screen (refer to your monitor's manual).



The picture quality is poor, with a dim picture, poor contrast, and poor sharpness. The monitor might be improperly adjusted.

Adjust the brightness, sharpness, and contrast controls of your monitor. Ensure that the cable is correctly and completely inserted at both ends. Make sure that the RGB input switches are set to 75 ohms.

The picture is broken up, with bad horizontal sync; in other words, it rolls, jitters, or blinks. The monitor's connections might be incomplete (that is, the cables connected to the monitor might not be attached properly), the monitor might not be properly adjusted, or the monitor might not accept M atrox Pulsar's video parameters.
s

E nsure that the synchronization line(s) are properly connected to your monitor (to identify the sync line(s), refer to the appropriate monitor configuration in the Connecting to a monitor section of Chapter 2). If this does not solve the problem, your monitor might need horizontal setting adjustments, or it might be defective. Refer to your monitor's manual. E nsure that the resolution you specified is valid for your monitor.

s

Problems running DOS programs
I cannot run DOS programs in Super VGA modes. M atrox Pulsar's on-board VGA is completely compatible with programs that use standard VGA and VESA modes. It is also compatible with Super VGA modes. However, if you experience problems running DOS programs in Super VGA modes, ensure that the program is compliant with version 1.2 of the VESA Super VGA standard. Some programs that are written to run in Super VGA modes are not VESA-compliant and depend on the specific chip used for the V GA. They are probably not compatible with Matrox Pulsar's VGA extended modes. Linking or compiling error under DOS To avoid running into this problem, install M IL-Lite (version 5.0 or greater) after installing Watcom Version 11.


Troubleshooting

65

Problems during application development
I want to overlay VGA data on image frame buffer data. Use the MIL-Lite command MdispOverlay() or the KEYWPUL utility (see Chapter 3 for more information on this utility), to set the M atrox Pulsar video keyer. The video keyer compares each pixel coming from the VGA to the reference color and, based on the result, routes either the VGA or the image frame buffer pixel to the display. I'm running an application and the system ` hangs' or produces unwanted results. Check for an interrupt, memory, or register conflict. Sometimes, an EISA or ISA device might attempt to use the same interrupts, register, or m emory space as Matrox Pulsar, and this causes a conflict. When I run an application, there is no picture on my video display. The monitor is blank. The application you are running m ight be attempting to select a resolution that isn't supported by your monitor. Check your monitor's manual for supported resolutions.

s

Frame A single image grabbed from a video camera.

s

Frame buffer A frame buffer is a dedicated storage area often used for data transfers between devices of differing speeds. For example, since a computer sends out data faster than a screen can display it, the data is temporarily stored in the frame buffer.

The Matrox BBS: Necessary information
s

The communication parameters are 28800, 19200, 14400, 9600, or 4800 baud (2400 baud is supported at specific times; contact your Matrox office for details), using 8 data bits, no parity and 1 stop bit. We have six practical peripheral modems that support up to 28.8 KBS. You will be prompted to enter your first and last names, and a password. If you don't have an account, one will be created for you when you enter your name. All files on our BBS are `zipped' using pkzip.exe. You can download this file, along with pkzipfix.exe, from the Download Pkware area on the BBS. You can upload files to your own private M atrox directory area. This is where we suggest you put any files that you would like us to examine or debug. No one other than the SYSOP (system operator) can see, upload to, or download from your private directory. Before uploading any file, please call Customer Support to notify them of your problem and ensure that your file receives prompt attention.
