Abstract:
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.
