Will write the filtered data in pcap format.
2) Are you peeling out the filter channel data from the pcap format and
arranging it ?

Ok, thanks for the suggestion, I'll try it out.

You would probably need to rework your down-stream stuff though.

Oh, that may be exactly what I need, I'll try it out.
Thanks!

Hi Jack,
I though of that, but the thing is, if I only take 1 sample per clock
cycle, I'm not sure how to use a 8 input FFT and still keep the same
number of output channels. Maybe I could implement serial-to-parallel
block, and read the FFT every 8 cycles, but I don't know if that's an
This is a bit hazy, but I think that might be because the processor
hasn't stopped properly - some permutation of rebooting, unplugging
and pressing the halt button on the GUI repeatedly sometimes helps.
Also check if the processor isn't running in an overclocked
configuration

Hey Franco
Many of the CASPER blocks were updated a while ago so that you can use them
asynchronously i.e data does not need to be fed to the blocks on every
clock cycle. You can then run your FPGA at a higher clock rate than the
input data rate.
