*	Description:	Vector unit slice which incorporates two vector	* 
*			unit standard datapaths, two multipliers and  	*
*			one control unit.  The register file is 	*
*			implemented in a seperate block from this vusl	*
*			and is hooked up at the top level.  This 	*
*			partitioning was decided upon for physical	*
*			partitioning.					*
*									*
*			This version is for the standard cell		*
*			implementation of the datapath.			*
