That seems odd, unless the in-place FFT is either slower, or internally uses an extra buffer.Does this mean that switching from out-of-place to in-place processing does NOT improve the performance? That might be interesting to know for certain processing steps... Translate 0 Kudo...
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...

An N-point Fast Fourier Transform (FFT) using mixed radix stages with in-place data sample storage may be performed by decomposing N into a product of R sequential mixed radix stages of radix-r(i). N data samples are partitioned into at least B memory banks, where B is equal to a ...

in-place FFT algorithm that adapts to thetarget architecture. For transform sizes where an in-place, in-order exe-cution is not possible, we show how schedules can be constructed thatuse minimum work-space to perform the computation efficiently. In or-der to express and construct FFT schedules...

Implementation of a self-sorting in-place prime factor FFT algorithm A "prime factor" Fast Fourier Transform algorithm is described which is self-sorting and computes the transform in place. With a view to implementation on a Cray-1 or Cyber 205, the form of the algorithm is chosen to minim...
A method for advancing pointers in a memory including a sequence of N data points of a stage M of a Fast Fourier Transform (FFT) whose first stage is stage 0, the N data points including N/2 a data points and N/2 B data points, the N data points are stored in the memory in 2M...
