Abstract
The present invention is directed to a method and apparatus for dispatching instructions in an information handling system. A pre-execution queue stores instructions, and at least one execution cluster is operably coupled to the pre-execution queue. An execution cluster comprises an early execution unit for executing a first instruction dispatched from the pre-execution queue to generate and forward a first result and a late execution unit for executing a second instruction dispatched from the pre-execution queue to generate and forward a second result after the first execution unit forwards the first result. The invention further includes circuitry operably associated with the pre-execution queue, and a method for prioritizing the order in which the instructions in the pre-execution queue are dispatched to the execution cluster.
