ABSTRACT:
A system and method of improved handling of large pages in a virtual memory system. A data memory management unit (DMMU) detects sequential access of a first sub-page and a second sub-page out of a set of sub-pages that comprise a same large page. Then, the DMMU receives a request for the first sub-page and in response to such a request, the DMMU instructs a pre-fetch engine to pre-fetch at least the second sub-page if the number of detected sequential accesses equals or exceeds a predetermined value.
