Abstract

A microprocessor architecture that includes capabilities for locking individual entries into its integrated instruction cache and data cache while leaving the remainder of the cache unlocked and available for use in capturing the microprocessor's dynamic locality of reference. The microprocessor also includes the capability for locking instruction cache entries without requiring that the instructions be executed during the locking process.
