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