Function Documentation

void DSP_urand16	(	unsigned short *restrict	seed,
		int	size,
		void *restrict	vector
	)

This program stores 16-bit fixed-point random values in the provided vector.

Parameters:

	seed	= Pointer to an arbitrary seed (number) of type unsigned short.
	size	= The size of the vector to be filled with random values.
	vector	= The vector to be filled with random values.

Algorithm:

A linear congruential 16-bit random number generator is used. The equation is as follows

seed = (seed * 46341 + 1) % 65536

See Numerical Recipes in C

Assumptions:

The size of the vector to be filled is at least 16 and a multiple of 2
For optimal randomness, it is best that the user not seed the RNG with a value of zero.

Implementation notes:

Endian Support: The code supports both big and little endian modes.
Interruptibility: The code is not interruptible.
