Abstract
The present invention is a method and apparatus to map virtual memory space. A region register file provides a region identifier for a virtual address in the virtual memory space. The virtual address includes a virtual region number and a virtual page number. A virtual page table look-up circuit is coupled to the region register file to generate a page table entry (PTE) virtual address from virtual address parameters. The virtual address parameters include the virtual address.
