A method for in-place memory management in a Digital Signal Processing (DSP) architecture performing a Fast Fourier Transformation (FFT) upon a sequence of N data points, the sequence numbered from 0 to N-1, the method including storing each of the data points numbered from 0 to (N/2)-...
I want to replace a slow in-place FFT with something from the IPP libraries. My application is processing audio, generally with 4K float samples per frame/ 4K FFT bins. Questions arising are:1. Ippsman.pdf indicates that ippsFFTFwd_CToC_32f_I() looks like a suitable replacement but does...
I am following the oneMKL 2D FFT code examples to perform a real to complex forward transform in-place. However, after the transform has been computed, the data does not appear to have changed. No errors are produced. Attempting to upload...

It has long been known that an in-place version of the Fast Fourier Transform (FFT) exists for real sequences of data. More recently, in-place FFTs have been devised for real sequences with even, odd, or quarter wave symmetries. All of these symmetric FFTs take the input sequence in sc...
