Detailed Description

void	DSPF_sp_vecmul (const float *x1, const float *x2, float *restrict y, const int nx)

Function Documentation

void DSPF_sp_vecmul	(	const float *	x1,
		const float *	x2,
		float *restrict	y,
		const int	nx
	)

This routine performs an element by element floating-point multiply of the vectors x1[] and x2[] and returns the values in y[].

Parameters:

	x1	Pointer to first input array.
	x2	Pointer to second input array.
	y	Pointer to output array.
	nx	Number of elements in arrays.

Algorithm:

DSPF_sp_vecmul_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 x1, x2 and y arrays must be double-word aligned
nx is a multiple of 4 and >= 4

Implementation Notes:

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