Abstract
An apparatus includes a context identification circuit and a translation lookaside buffer (TLB) circuit. The context identification circuit may be configured to receive a context identifier assigned to a process being executed by a processor, and to assign a rename value to the context identifier that has fewer bits than the context identifier. The TLB circuit may be configured to receive a translation request for a virtual address that is associated with the process. The TLB circuit may be further configured to cache a translation of the virtual address to a corresponding physical address. The given entry may be tagged with a portion of the virtual address and the rename value. In response to a subsequent translation request for the virtual address, the TLB circuit may detect, using the portion of the virtual address and the rename value, a hit on the given entry of the TLB circuit.
