Function Documentation

void DSP_w_vec	(	const short *restrict	x,
		const short *restrict	y,
		short	m,
		short *restrict	r,
		int	nr
	)

This routine is used to obtain the weighted vector sum. Both the inputs and output are 16-bit numbers

Parameters:

	x	= Vector being weighted
	y	= Summation vector
	m	= Weighting factor
	r	= Output vector
	nr	= Dimensions of the vectors

Algorithm:

DSP_vecsumsq_cn.c is the natural C equivalent of the optimized intrinsic C code without restrictions note that the intrinsic C code is optimized and restrictions may apply.

Assumptions:

nr must be a multiple of 8 and >= 8.
Vectors x[ ] y[ ] and r[ ] must be double-word aligned.
m is not -32768.

Implementation notes:

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