    摘要： According to one embodiment of the invention, an activity detector comprises a resource partitioned into a plurality of chunks, a power controller and an activity detection unit. In communication with the activity detector and the resource, the power controller, based on measured activity by the activity detector, activates an additional chunk of the plurality of chunks and assigned the additional chunk to a specified agent or deactivates at least one chunk of the plurality of chunks.

    摘要： Snoop filtering methods and apparatuses for systems utilizing memory are contemplated. Method embodiments comprise receiving a request for contents of a memory line by a home agent, comparing an address of the memory line to a range in a set of adaptive ranges, and snooping an I/O agent for the contents upon a match of the address within the range. Apparatus embodiments comprise a range table, a table updater, a receiver module, and a range comparator. The range tables allow for the tracking of memory addresses as I/O agents assert ownership of the addresses. Employing a range-based snoop filtering approach may allow home agents to track a collection of addresses, in adaptable ranges, instead of tracking precise addresses which may require large quantities of memory to implement.
