SYSTEM AND METHOD FOR PAGE-BY-PAGE MEMORY CHANNEL INTERLEAVING

摘要

Systems and methods are disclosed for providing memory channel interleaving with selective power or performance optimization. One such method comprises configuring a memory address map for two or more memory devices accessed via two or more respective memory channels with an interleaved region and a linear region. The interleaved region comprises an interleaved address space for relatively higher performance tasks. The linear region comprises a linear address space for relatively lower power tasks. A request is received from a process for a virtual memory page. The request comprises a preference for power savings or performance. The virtual memory page is assigned to a free physical page in the linear region or the interleaved region according to the preference for power savings or performance.

1. A memory channel interleaving method with selective power or performance optimization, the method comprising:
configuring a memory address map for two or more memory devices accessed via two or more respective memory channels with an interleaved region and a linear region, the interleaved region comprising an interleaved address space for relatively higher performance tasks and the linear region comprising a linear address space for relatively lower power tasks; receiving a request from a process for a virtual memory page, the request comprising a preference for power savings or performance; and assigning the virtual memory page to a free physical page in the linear region or the interleaved region according to the preference for power savings or performance.
