ABSTRACT:
A method and apparatus in a superscalar microprocessor for early completion of floating-point instructions prior to a previous load/store multiple instruction is provided. The microprocessor's load/store execution unit loads or stores data to or from the general purpose registers, and the microprocessor's dispatch unit dispatches instructions to a plurality of execution units, including the load/store execution unit and the floating point execution unit. The method comprises the dispatch unit dispatching a multi-register instruction to the load/store unit to begin execution of the multi-register instruction, wherein the multi-register instruction, such as a store multiple or a load multiple, stores or loads data from more than one of the plurality of general purpose registers to memory, and further, prior to the multi-register instruction finishing execution in the load/store unit, the dispatch unit dispatches a floating-point instruction, which is dependent upon source operand data stored in one or more floating-point registers of the plurality of floating point registers, to the floating-point execution unit, wherein the dispatched floating-point instruction completes execution prior to the multi-register instruction finishing execution.
