Function Documentation

void csky_bitreversal_f32	(	float32_t *	pSrc,
		uint16_t	fftSize,
		uint16_t	bitRevFactor,
		uint16_t *	pBitRevTab
	)

void csky_cfft_radix4_f32	(	const csky_cfft_radix4_instance_f32 *	S,
		float32_t *	pSrc
	)

Deprecated:

Do not use this function. It has been superseded by csky_cfft_f32 and will be removed in the future.

Parameters

[in]	*S	points to an instance of the floating-point Radix-4 CFFT/CIFFT structure.
[in,out]	*pSrc	points to the complex data buffer of size 2*fftLen. Processing occurs in-place.

Returns

none.
