I would like to re-inforce this suggestion if
Thanks for that, Jason! It is very timely. The reason I went down this
path is because I have a spectrometer design, by Joseph Trinh, which
takes a slightly different approach to bram access and so I could not
use the katcp_wrapper which I'd been using with your 16K spectrometer.

If you take a look at the pocket correlator design (tutorial 4), you'll find
that it does four inputs of 400MHz bandwidth (800Msps). I think it has 4-tap
PFBs with 1024 channels by default, which fits into a ROACH-1. If you forfeit
two of the inputs, you should be able to get at least twice the

Trying to clock the FPGA at 320MHz will be tricky, so I'd suggest just demux
again and run it at 160MHz. I believe that you should have enough resources to
do this with at least a 4-tap PFB and 1024 channels. 2-inputs at 800MHz is
equivalent to 4-inputs at 400MHz in terms of processing load. The

These should help

hi tom,
you might consider using the vegas mode 1 spectrometer design:
1024 channels, dual pol, 1.5 GHz bandwidth (3 Gsps),
full stokes, roach I, 4 tap polyphase,
best wishes,
dan
