Abstract:
A method for reducing entries searched in a load reorder queue (LRQ) when snoop instructions are executed by a processor, including checking load reorder queue (LRQ) entries located between a load_peril_snoop register and a lrq_tail register for addresses matching the address of the snoop; and setting a snooped bit in the LRQ entry for any matches found.
