nrf_dsp_cfft_i16()

void nrf_dsp_cfft_i16	(	const nrf_dsp_cfft_i16_t *	p_cfft,
		int16_t *	p_input,
		uint8_t	bitreverse_flag )

#include <include/nrf_edgeai/dsp/transform/fft/nrf_dsp_fft_i16.h>

The fixed-point 16-bit complex FFT function.

Note

The FFT computes in-place and will modify input buffer with FFT results. The results will be written to input array in the interleaved fashion:

{real[0], imag[0], real[1], imag[1], ...} 

Parameters

[in]	p_cfft	Pointer to instance of complex FFT structure
[in,out]	p_input	Pointer to buffer with input samples.
[in]	bitreverse_flag	Flag that enables (bitreverse_flag=1) or disables(bitreverse_flag=0) bit reversal of output
