Abstract
Systems and methods are disclosed for store-to-load forwarding for processor pipelines. For example, an integrated circuit (e.g., a processor) for executing instructions includes a processor pipeline; a store queue that has entries associated with respective store instructions that are being executed, wherein an entry of the store queue includes a tag that is determined based on a virtual address of a target of the associated store instruction; and store-to-load forwarding circuitry that is configured to: compare a first virtual address of a target of a first load instruction being executed by the load unit to respective tags of one or more entries in the store queue; select an entry of the store queue based on a match between the first virtual address and the tag of the selected entry; and forward data of the selected entry in the store queue to be returned by the first load instruction.
