Abstract
A memory request issue counter (MRIC) is maintained that is incremented for every memory access a central processing unit core makes. A region reuse distance table is also maintained that includes multiple entries each of which stores the region reuse distance for a corresponding region. When a memory access request for a physical address is received, a reuse distance for the physical address is calculated. This reuse distance is the difference between the current MRIC value and a previous MRIC value for the physical address. The previous MRIC value for the physical address is the MRIC value the MRIC had when a memory access request for the physical address was last received. A region reuse distance for a region that includes the physical address is generated based on the reuse distance for the physical address and used to manage the cache.
