Abstract
The disclosed data processor (10) dispatches load/store multiple and load/store string instructions to a load/store unit (28) as a sequence of simple load or store instructions. The sequencer unit (18) assigns an entry of a rename buffer (34) to which the load/store unit writes back the data of each simple load instruction. This strategy facilitates early data forwarding for subsequent instructions. Conversely, the sequencer unit supplies a rename buffer tag to the load/store unit if it is not able to supply the operands of a simple store instruction.
