Function Documentation

int DSP_dotprod	(	short *restrict	x,
		short *restrict	y,
		int	nx
	)

This routine takes two vectors and calculates their dot product. The inputs are 16-bit short data and the output is a 32-bit number.

Parameters:

	x	= First vector array
	y	= Second vector array
	nx	= Number of elements

Algorithm:

DSP_dotprod_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:

The input length must be a multiple of 4.
The input data x[] and y[] are stored on double-word aligned boundaries.

Implementation notes:

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