Abstract

In a load/store unit within a microprocessor, load instructions are executed out of order. The load instructions are assigned tags in a predetermined manner, and then assigned to a load reorder queue for keeping track of the program order of the load instructions. Then when new load instructions are issued, the new load instructions are compared to entries within the load reorder queues to detect out of order problems.
