摘要:
Methods and apparatus for inclusion of TLB (translation look-aside buffer) in processor micro-op caches are disclosed. Some embodiments for inclusion of TLB entries have micro-op cache inclusion fields, which are set responsive to accessing the TLB entry. Inclusion logic may the flush the micro-op cache or portions of the micro-op cache and clear corresponding inclusion fields responsive to a replacement or invalidation of a TLB entry whenever its associated inclusion field had been set. Front-end processor state may also be cleared and instructions refetched when replacement resulted from a TLB miss.
