I have read, but not tested on big iron, that the "butterfly transform" 
gives compatible results with a lot less big iron to do it.

I fooled with it 20 years ago on a big box amiga, it worked, but I couldn't 
compare to the same depth of FFT because I couldn't find free FFT that SAS 
C-6.58 would build.
