    摘要: A computing system performs partial cache deactivation. The computing system estimates the leakage power of a cache based on operating conditions of the cache including voltage and temperature. The computing system further identifies a region of the cache as a candidate for deactivation based on cache hit counts. The computing system then adjusts the size of the region for the deactivation based on the leakage power and a bandwidth of a memory hierarchy device. The memory hierarchy device is at the next level to the cache in a memory hierarchy of the computing system.
