Low Power Shared Cache Reconfigurable Method for Multicore Processor

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%.
