METHOD, APPARATUS, AND SYSTEM FOR ENERGY EFFICIENCY AND ENERGY CONSERVATION INCLUDING DYNAMIC CACHE SIZING AND CACHE OPERATING VOLTAGE MANAGEMENT FOR OPTIMAL POWER PERFORMANCE |
摘要 |
Embodiments of the invention relate to increased energy efficiency and conservation by reducing and increasing 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.
