I'm trying to find a 64-point FFT/IFFT core. Target is Actel IGLOO family. Needs to run fast enough to complete in 3.2us, which is tough in an IGLOO. Actel has a free FFT core but it is not quite fast enough. It's a radix-2 core, which is not optimal for this application. Radix-4 would be better. I've looked at the cfft core on Opencores and it may work for us, but also want to check commercial options. Thanks, Rob
