ABSTRACT:
In a superscalar data processing system, instructions, which are dependent upon each other, are paired for dispatch to a plurality of execution units. Pairing results in instructions being paired that may not necessarily be located at contiguous addresses. Pairing may be performed by comparing general purpose register source pointers and general purpose register target pointers of the various instructions. Pairing may also be accomplished by comparing target identification numbers of source operands with target identification numbers of target instructions.
