hi andrea,
you might be interested in other roach based seti systems:
laura spitler ported the 128 million channel bee2 seti spectrometer
to roach, and terry filiba developed a roach/GPU seti spectrometer,
where roach digitizes data, breaks it up into sub-bands using a polyphase
filter bank, and sends each sub-band to a cpu/gpu for high resolution
spectroscopy.
best wishes,
dan

Hi All,
I'm a Medicina Radiotelescopes (Italy) team member, my name is Andrea
Mattana, I'm working here since January to develop a new acquisition
system for SETI based on the CASPER ROACH board.
I have started to work using the libraries available on the SVN
repository and in June I have done the migration on GIT following your
instractions and now I'm very up-to-date.
I have some problems in using the CASPER FFT libraries, the drawings
seems to do not update after changing parameters. When I try to look
under mask (i.e. on fft_biplex_real_2x) there are no connections at all
between blocks, while many other casper blocks works nominally. I have
seen on the GIT commit log an update done by David MacMahon on those
blocks, I don't know if he is the right person that can help me anyway
I'm very happy to hear any suggestion to fix the problem from you all.
The developing system I use it is a Linux Centos release 5.5 64 bit,
Matlab R2009b, Xilinx 11.4.
Kind regards,
Andrea Mattana
