Abstract :
A method for reducing the power consumption of set-associative caches is proposed. The method tracks the way information of all cache blocks and allows access of only those ways that potentially contain the requested block. When used for a 512KB eight-way 64B-block L2 cache, the method reduces the energy consumption by 79%.
