PROCESSOR, CONTROL METHOD OF MULTI-LEVEL CACHE MEMORY, AND CONTROL PROGRAM OF MULTI-LEVEL CACHE MEMORY

摘要

To provide a processor capable of suppressing electrical power consumption while maintaining or improving application execution performance.SOLUTION: The processor includes: a cache memory having multiple layers; and a determination part that determines whether or not the cache memory in the first layer should be enabled on the basis of the contribution of the cache memory of the first layer, which is calculated on the basis of value based on the power efficiency, a state of the cache memory in the first layer included in the multiple layers, and the state of the cache memory of a second layer different from the first layer included in the multiple layers.SELECTED DRAWING: Figure 1
