ABSTRACT:
A method and system for resolving virtual addresses using a page size tag are described herein. In one embodiment, the method comprises translating a virtual memory address into physical memory address. According to the method, the translating includes producing a first page size tag and choosing an entry in a translation lookaside buffer, wherein the entry stores a second page size tag and a page frame number. The method also includes comparing the first page size tag with the second page size tag. The method also includes using the page frame number to form the physical memory address, if the first page size tag is less than or equal to the second page size tag.
