VARIABLE PAGE SIZE TRANSLATION LOOKASIDE BUFFER

摘要

A set associative translation lookaside buffer (TLB) (100) that supports variable sized pages without requiring the use of a separate block TLB. The TLB includes a hashing circuit (108) that creates an index into the TLB for a virtual address (300) using different bits from the virtual address depending on the page size of the address, and a comparing circuit (500) that compares virtual address identifiers or portions of virtual address identifiers (200) stored in the TLB to the current virtual address to determine if a translation to the current virtual address is stored in the TLB.
