ABSTRACT:
A method and apparatus for reordering memory requests for page coherency. Various data streams are frequently found in separate areas of physical memory (i.e. each data stream is found in a separate memory “page”). Because these requests from different streams become intermixed, a certain amount of latency results from the resulting page “breaks.” These page breaks occur when consecutive requests are from different data streams, requiring accesses to different memory pages. When several separate streams of data are requested by a client, page coherency between requests diminishes. A reordering device regains lost page coherency, thereby reducing the amount of latency and increasing overall system performance.
