Hey all,
Luke Madden was asking me about what's going on in the FFT-direct today.
I'm pretty sure we have basically zero documentation on this lying around,
so it's a good time to fix that. I'm going share what I know, but I'd
appreciate it if other people could add/correct me as needed.
Hi Ryan,
I wrote the various forms of the CASPER FFT, including this one. The broad
idea of the architecture was described in:

Basically, (as far as I can tell from the brief perusal of split-radix
ffts), I think this *is* a
Hey Aaron!
My understanding may be imperfect, but I thought that a split-radix FFT
would have a bank of phase rotations (one for each input to fft-direct)
after the biplex FFTs. If you chose your phase rotation coefficients
correctly, you'd be able to finish the larger FFT with a simple

That makes two of us! Viva la revolution!
