Re: [casper] number of coefficients needed in PFB and FFT

[Andrew Martens]

Hi Dave
Do you have any utilization comparisons of old vs new?
Not yet, I hope to do a basic one soon though. Savings will depend on 
use case. Also, you can optimise for resources in a few ways (DSPs vs 
BRAMs when using fft_direct, logic vs BRAMS in the biplex stages and in 
"reset point" storage in fft_direct). Bit growth could be used to save 
on logic at the expense of some signal to noise.

Cheers
Andrew
