ABSTRACT:
A microprocessor is provided, including a plurality of early decode units configured to detect double dispatch instructions and to dispatch these instructions to a pair of decode units. More complex instructions are executed by an MROM unit in a serialized fashion. Simpler instructions are dispatched to a single decode unit. The early decode units partially decode the instructions (including encoding the instruction prefix into a single prefix byte), and the decoding is completed by a plurality of decode units. The present microprocessor additionally detects the more complex instructions prior to instruction decode and dispatches the instructions to an MROM unit.
