Method and Apparatus For Deterministic Translation Lookaside Buffer (TLB) Miss Handling
Abstract:
An apparatus and method are described for translation lookaside buffer (TLB) miss handling. For example, one embodiment of a processor comprises: a translation lookaside buffer (TLB) to store virtual-to-physical address translations; a page miss handler (PMH) to process TLB misses when a desired virtual-to-physical address translation is not present in the TLB; and a compressed page table to be managed by the PMH, the compressed page table to store specified portions of page tables, wherein in response to a TLB miss for a first address translation, the PMH is to check the compressed page table to determine if a page table entry corresponding to the first address translation is stored therein and, if so, to provide the first address translation from the compressed page table.
