    摘要: Embodiments described herein vary an amount of cache available for use by a processor, and an amount of power supplied to the cache and to the processor, based on the amount of cache actually being used by the processor to process data. For example, a power control unit (PCU) may monitor a last level cache (LLC) to identify if the size or amount of the cache being used by a processor to process data and to determine heuristics based on that amount. Based on the monitored amount of cache being used and the heuristics, the PCU causes a corresponding decrease or increase in an amount of the cache available for use by the processor, and a corresponding decrease or increase in an amount of power supplied to the cache and to the processor.

    摘要: In one embodiment, the present invention includes a processor having a first domain with a first compute engine and a second domain with a second compute engine, where each of these domains can operate at an independent voltage and frequency. A first logic may be present to update a power bias value used to control dynamic allocation of power between the first and second domains based at least in part on a busyness of the second domain. In turn, a second logic may dynamically allocate at least a portion of a power budget for the processor between the domains based at least in part on this power bias value. Other embodiments are described and claimed.
