vsip_ccfftip_p - Perform FFT Operations (In-Place)

Core

5.1.6 vsip_ccfftip_p - Perform FFT Operations (In-Place)

void vsip_ccfftip_f(const vsip_fft_f *fft, const vsip_cvview_f *y);

Description

These functions perform FFT (Fast Fourier Transform) operations using the specified FFT object in-place.

The performance for supported FFT sizes is standardized as $O(nlogn)$ . For sizes not directly supported by the FFT kernels a DFT fallback with a performance of $2 O(n )$ is standardized.

Parameters

const vsip_fft_p* fft: Pointer to the FFT object.
const vsip_cvview_p* y: Pointer to the complex input and output vector view.
