  • System and method for permitting out-of-order execution of load and store instructions
    Patent number: 6301654
    Abstract: In a load/store unit within a microprocessor, load and store instructions are executed out of order. The load and store instructions are assigned tags in a predetermined manner, and then assigned to load and store reorder queues for keeping track of the program order of the load and store instructions. Then when new load or store instructions are issued, the new load or store instructions are compared to entries within the load and store reorder queues to detect out of order problems.
