Hi all, one can download the code for an N-point real FFT (for the 65L SHARC) from the ADI webpage. It transforms N real values into N/2+1 complex values (the other N/2-1 complex values follow by hermitian symmetry). I'm looking for the inverse, ie. IFFT of N/2+1 complex values assuming hermitian symmetry, resulting in N real values. Of course, I could use a complex N-point IFFT (also downloadable from the ADI webpage) and discard the imaginary output, but I want to capitalize from the hermitian symmetry of my data. Does anybody have such code (optimized for SHARC architecture)? Regards, Andor
