Hi all,
- I am looking for a highly optimized FFT code for size 32k.
I already know Apples OpenCL FFT implementation, but I thought there must be something better, since I don’t need a general purpose algorithm, but only size 32k.
- I am also looking for an FFT algorithm that can take advantage of the fact that the input data is either -1 or +1 (well, to be more precise, since it’s complex numbers, it’s {{-1,-1}, {-1,+1}, {+1,-1}, {+1,+1}} ).
Any ideas?
Cheers,
F.
