Fasti - SVB, The Flexible Sequence Generator

Central to Fasti is SVB, The Flexible Sequence Generator. It is based on a specialized micro-controller, where the waveform are described by means of a program in a pseudo assembler language.

Among their feature are:

• It can hold four independent clocking schemes, which can be selected on a per integration basis. It is also completely reprogrammed in few seconds.
• It is completely controlled by a standard serial interface.
• It is a conceptual design, so can be easily ported from present components (XC95288) to future, more powerful components.
• Its present time division is 62nsec (16Mhz), but can scale up easily.
• It can accommodates up to 4096 instructions, with looping capabilities (5 nested levels).
• It has synchronous start/stop.
