Abstract
A method for translating a virtual memory address into a physical memory address includes parsing the virtual memory address into a page directory entry offset, a page table entry offset, and an access offset. The page directory entry offset is combined with a virtual memory base address to locate a page directory entry in a page directory block, wherein the page directory entry includes a native page table size field and a page table block base address. The page table entry offset and the page table block base address are combined to locate a page table entry, wherein the page table entry includes a physical memory page base address and a size of the physical memory page is indicated by the native page table size field. The access offset and the physical memory page base address are combined to determine the physical memory address.
