Abstract
A device is described by this disclosure for performing memory stores in a memory of a computer system. The computer system includes a processor having a pipeline for processing commands in multiple stages; wherein the commands include a plurality of instructions, including store instructions, and virtual addresses. When the processor processes a store command, the pipeline is blocked until the associated virtual address is translated by a translation device to a real address. In the present device, if a selected store operation is processed, a check is made to see if the associated virtual address has previously been translated, and if it has, the pipeline is unblocked, thus enhancing the processing of store operations.
