TRANSLATION LOOKASIDE BUFFER WITH PARTIAL TAG HASHED ACCORDING TO PAGE SIZE INDICATOR

摘要

A translation lookaside buffer (TLB) is disclosed formed using RAM and synthesisable logic circuits. The TLB provides logic within the synthesisable logic for pairing down a number of memory locations that must be searched to find a translation to a physical address from a received virtual address. The logic provides a hashing circuit for hashing the received virtual address and uses the hashed virtual address to index the RAM to locate a line within the RAM that provides the translation.
