Processor memory optimization via page access counting

Abstract

To utilize the most efficient memory available to a mobile processor, page access counters may be used to record utilization associated with multiple different memory types. In one embodiment, an operating system routine may analyze the page access counters to determine low utilization pages and high utilization pages to dynamically assign between the multiple different memory types, which may include a more efficient memory type having greater capacity, greater throughput, lower latency, or lower power consumption than a less efficient memory type. As such, in response to detecting a high utilization page in the less efficient memory or a low utilization page in the more efficient memory, contents associated therewith may be copied to the more efficient memory and the less efficient memory, respectively, and virtual-to-physical address mappings may be changed to reflect the reassignment.
