Description

Function Documentation

void csky_split_rfft_f32	(	float32_t *	pSrc,
		uint32_t	fftLen,
		float32_t *	pATable,
		float32_t *	pBTable,
		float32_t *	pDst,
		uint32_t	modifier
	)

Parameters

[in]	*pSrc	points to the input buffer.
[in]	fftLen	length of FFT.
[in]	*pATable	points to the twiddle Coef A buffer.
[in]	*pBTable	points to the twiddle Coef B buffer.
[out]	*pDst	points to the output buffer.
[in]	modifier	twiddle coefficient modifier that supports different size FFTs with the same twiddle factor table.

Returns

none.
