DATA MIGRATION METHOD, DEVICE AND PROCESSOR

摘要

In embodiments of the present invention, an on-chip memory in a many-core system is partitioned, and according to a frequency at which a processor core set in each on-chip partition accesses a virtual memory page in virtual memory space that is shared among multiple processes that belong to a same application program, data corresponding to the virtual memory page is moved to an on-chip memory partition in which a processor core set whose access frequency is high is located, so that when the virtual memory page is subsequently accessed, a time delay caused by cross-partition access is reduced.
