Abstract:
A technique to allow independent loads to be satisfied during high-latency instruction processing. Embodiments of the invention relate to a technique in which a storage structure is used to hold store operations in program order while independent load instructions are satisfied during a time in which a high-latency instruction is being processed. After the high-latency instruction is processed, the store operations can be restored in program order without searching the storage structure.
