METHOD FOR ADAPTIVE ARBITRATION OF REQUESTS FOR MEMORY ACCESS IN A MULTI-STAGE PIPELINE ENGINE

In a method for adaptive arbitration of requests for accessing a memory unit in a multi-stage pipeline engine that includes a plurality of request queues corresponding to the stages of the pipeline engine, each of the request queues is assigned to one of a high-priority group and a low-priority group in accordance with an operating state of the memory unit. The request queues in the high-priority group are then processed prior to the request queues in the low-priority group.
