ADDRESS RANGE PRIORITY MECHANISM

摘要

Method and apparatus to efficiently manage data in caches. Data in caches may be managed based on priorities assigned to the data. Data may be requested by a process using a virtual address of the data. The requested data may be assigned a priority by a component in a computer system called an address range priority assigner (ARP). The ARP may assign a particular priority to the requested data if the virtual address of the requested data is within a particular range of virtual addresses. The particular priority assigned may be high priority and the particular range of virtual addresses may be smaller than a cache's capacity.
