SYSTEMS AND METHODS FOR ACCESSING A UNIFIED TRANSLATION LOOKASIDE BUFFER

摘要

Systems and methods for accessing a unified translation lookaside buffer (TLB) are disclosed. A method includes receiving an indicator of a level one translation lookaside buffer (L1TLB) miss corresponding to a request for a virtual address to physical address translation, searching a cache that includes virtual addresses and page sizes that correspond to translation table entries (TTEs) that have been evicted from the L1TLB, where a page size is identified, and searching a second level TLB and identifying a physical address that is contained in the second level TLB. Access is provided to the identified physical address.

1. A method for accessing a unified translation lookaside buffer (TLB), comprising:
in response to receiving an indicator of a level one translation lookaside buffer (L1TLB) miss corresponding to a request for a virtual address to physical address translation, searching a cache comprising virtual addresses and page sizes that correspond to translation table entries (TTE's) that have been evicted from said L1TLB, wherein a page size is identified; and based on said identified page size, searching a second level TLB and identifying a physical address therein.
