Abstract:
Address translation performance within a processor is improved by identifying an address that causes a boundary crossing between different pages in memory and linking address translation information associated with both memory pages. According to one embodiment of a processor, the processor comprises circuitry configured to recognize an access to a memory region crossing a page boundary between first and second memory pages. The circuitry is also configured to link address translation information associated with the first and second memory pages. Thus, responsive to a subsequent access the same memory region, the address translation information associated with the first and second memory pages is retrievable based on a single address translation.
