SHARC inverse RFFT

Started by andor_bariska May 2, 2005
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)?
