HARDWARE-BASED PRE-PAGE WALK VIRTUAL ADDRESS TRANSFORMATION

摘要

An apparatus includes a processor and a virtual address transformation unit coupled with the processor. The virtual address transformation unit includes a register. The virtual address transformation unit is configured to receive an indication of a virtual address and read, from the register, a current page size of a plurality of available page sizes. The virtual address transformation unit is also configured to determine a shift amount based, at least in part, on the current page size and perform a bit shift of the virtual address, wherein the virtual address is bit shifted by, at least, the determined shift amount.
