Hi Katty
Hi all,
When the number of parallel spectrometers increases when one decreases
the number of channels, but surprisingly, this increase is not very
significant, why resources not decreases significant from 32 to 2048
channels and where do the resources, FFt, PFB? and like to know how
many resource occupies FFt and PFB? In the file xflow.log described
design summary ( number lut, flipflop , slices, etc) but no many
resources occupies FFt and PFB?
I would advise you to search through the mail archives at
http://www.mail-archive.com/[email protected]/ whenever you have
a question, it has often been answered before :) In this case
http://www.mail-archive.com/[email protected]/msg04161.html
points you to a nice bit of work the Harvard crowd did to analyse this.
Note that work is being done to significantly reduce resource usage in
the PFB (especially BRAM), so the final values may change a little.
Regards
Andrew
