Special Requirements

-Input and output arrays do not overlap, except when “r == NULL” so that the operation occurs in-place.

-The input array and output array are expected to be double-word aligned, and a multiple of 2 double-words must be processed.

Implementation Notes

	- Bank Conflicts: No bank conflicts occur.
	- Interruptibility: The code is interrupt-tolerant but not interruptible.
