ABSTRACT:
The illustrative embodiments described herein provide a computer implemented method, apparatus, and computer program product for increasing a number of instructions per clock cycle associated with a processor. The illustrative embodiments fold a plurality of non-sequential instructions within the set of sequential order instructions to form a folded instruction. The folded instruction is executed to form an executed instruction. The executed instruction is placed in a reorder buffer. The instructions within the reorder buffer are written to a register based on the sequential order of execution within the set of sequential order instructions.
