Function Documentation

void DSP_neg32	(	const int *restrict	x,
		int *restrict	r,
		int	nx
	)

This function negates the elements of a vector (32-bit elements). The input and output arrays must not be overlapped except for where the input and output pointers are exactly equal

Parameters:

	x	= Pointer to input data vector of size nx with 32-bit elements
	r	= Pointer to output data vector of size nx with 32-bit elements
	nx	= Number of elements of input and output vectors

Algorithm:

DSP_neg32_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.
The arrays x[ ] and r[ ] must be double-word aligned.

Implementation notes:

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