MICROPROCESSOR WITH APPARATUS AND METHOD FOR REPLAYING LOAD INSTRUCTIONS

A processor includes a time counter and a time-resource matrix and provides a method for statically dispatching load/store instructions if the required resources are available based on data stored in the time-resource matrix, and wherein execution times for the load/store instructions use a time count from the time counter to specify when the load/store instructions may be provided to a load-store unit pipeline. The execution times of the load instruction is based on the data cache hit latency time. A delay of the load/store instruction causes the load/store instruction to be replayed with known or estimated time. A load-store unit employs multiple bank queues to access multiple data banks of a data cache.
