  • Patent number: 6970978
    Abstract: A system and method is disclosed for providing a pre-fetch memory controller in a computer system that comprises a plurality of master agents. The memory controller comprises a bus interface, a memory interface and a plurality of pre-fetch queues. In one embodiment each pre-fetch queue is assigned to a master agent. In an alternate embodiment the pre-fetch queues are dynamically assigned to master agents. The bus interface services memory read requests, memory write requests, and pre-fetch requests. Data may be pre-fetched from main memory and stored in the pre-fetch queues. This reduces the latency for memory read requests and improves the efficiency of the memory interface with the main memory.
