Abstract
A page directory entry cache (PDEC) can be checked to potentially rule out one or more possible page sizes for a translation lookaside buffer (TLB) lookup. Information gained from the PDEC lookup can reduce the number of TLB checks required to conclusively determine if the TLB lookup is a hit or a miss.
