ABSTRACT:
One or more methods and systems of improving the performance of consecutive data stores into a cache memory are presented. In one embodiment, the method comprises writing data into a data array associated with at least a first store instruction while accessing a tag in a tag array associated with at least a second store instruction. In one embodiment, the method of processing consecutive data stores into a cache memory comprises updating a first data in a cache memory while concurrently looking up or identifying a second data in the cache memory. In one embodiment, a system for improving the execution of data store instructions of a CPU comprises a pipelined buffer using a minimal number of data entries, a data array used for updating data associated with a first store instruction, and a tag array used for looking up data associated with a second store instruction.
