多核处理器共享Cache低功耗可重构方法

摘要

为了降低整个处理器的功耗,分析了当前多核Cache低功耗技术,并提出一种面向多核共享Cache低功耗的重构方法.在共享Cache上进行静态重构,分析了Cache重构的必要性,然后在Cache访问的过程中加入重构策略.实验结果证明:在性能平均损失4％的情况下,功耗平均降低了18％左右.%To reduce the power consumption,the technology about cache low power was analysed,and a shared cache reconfigurable method in the multi-core processors (CMP) for low power was proposed.First,the cache reconfiguration necessity by the static reconfiguration was analysed; Then,the reconfigurable strategy during cache access was added.Result shows that the method can save about 18％ energy consumption,while the performance decline is only 4％.
