Function Documentation

void DSPF_sp_biquad	(	float *restrict	x,
		float *	b,
		float *	a,
		float *	delay,
		float *restrict	y,
		const int	nx
	)

This routine implements a DF 2 transposed structure of the biquad filter

Parameters:

	x	Pointer to input samples
	b	Pointer to Nr coefs b0, b1, b2
	a	Pointer to Dr coefs a1, a2
	delay	Pointer to filter delays
	y	Pointer to output samples
	nx	Number of input/output samples

Algorithm:

DSPF_sp_biquad_cn.c is the natural C equivalent of the optimized linear assembly code without restrictions. Note that the linear assembly code is optimized and restrictions may apply.

Assumptions:

The value of nx is >= 2.

Implementation Notes:

Interruptibility: The code is interruptible.
Endian Support: The code supports both big and little endian modes.
