Function Documentation

void DSPF_sp_convol	(	const float *	x,
		const float *	h,
		float *restrict	y,
		const short	nh,
		const short	ny
	)

This function calculates the full-length convolution of real vectors x and h using time-domain techniques. The result is placed in real vector y. It is assumed that input vector x is padded with nh-1 no of zeros in the beginning and end.

Parameters:

	x	Pointer to real input vector of size = nr+nh-1.
	h	pointer to real input vector of size nh in forward order.
	y	Pointer to real output vector of size ny.
	nh	Number of elements in vector h.
	ny	Number of elements in vector y.

Algorithm:

DSPF_sp_convol_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:

nh is a multiple of 2 and greater than or equal to 4.
ny is a multiple of 4.
x, h and y are assumed to be aligned on a double-word boundary.

Implementation Notes:

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