Function Documentation

int DSP_vecsumsq	(	const short *	x,
		int	nx
	)

This routine returns the sum of squares of the elements contained in the vector x[ ]. return Sum of the squares.

Parameters:

	x	= Pointer to input data vector
	nx	= Number of elements of input and output 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:

nx must be a multiple of 4 and greater than or equal to 4.
x must be double-word aligned.

Implementation notes:

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