Abstract:
A processor including a microarchitecture adapted for invalidating mapping of at least one logical address to at least one absolute address, includes: at least one translation lookaside buffer (TLB) and a plurality of copies thereof; logic for independent indexing of each copy of the TLB; a plurality of comparators, each comparator associated with a respective output of each TLB set output for each TLB port, wherein each of the comparators is adapted for identifying mappings for invalidation; and logic for invalidating each identified mapping. A method and a computer program product are provided.
