Hi,I'm implementing a filtering using FFT. ( but it's not in a conventional way)Comparing the conventional method with my algorithm, I had a guestion about FFT in IPP.According to my simulation results, N point complex FFT has the same pBuffer size asa 2N point real FFT. To be specific, two functions are ippsFFTFwd_CToC_32fc and ippsFFTFwd_RToPerm_32f. But in all lengths, N point complex FFT is faster than 2N point realFFT in spite of same pBuffer sizes.I want to know the reason for that..
