The Puertorican Ultimate Pulsar Processing Instrument (PUPPI) is a backend built with off-the-shelf hardware designs, and custom FPGA "Gateware". This gateware is compiled and loaded into the 7 Xilinx FPGA's used for PUPPI's implementation. It is a clone of the NRAO Green Bank GUPPI.
For the March 2012 proposal deadline, the PUPPI backend will be
available in shared risk mode to expert users of the GUPPI backend at
the GBT. It is expected that by the September 2012 deadline, PUPPI will
be fully integrated into the Arecibo observing software, and non-expert
users will be encouraged to apply. In search mode, the PUPPI backend
provides a maximum bandwidth of 800 MHz, up to 2048 spectral channels,
and 40.96 microsec minimum sampling time. In addition, 20.48 microsec
sampling is possible in on-line folding mode. For more details,
potential users can refer to the GUPPI on-line manual at
