Abstract: Abstract This article introduces a cache management policy named FLEXII. It can reduce the number of dead-on-fill blocks, which are not reused until they are evicted from cache memories. Since these blocks do not contribute to performance improvement, they limit the energy saving achieved by dynamic cache resizing mechanisms, which will play key roles to improve the energy efficiency of future microprocessors. The evaluation results show that, by eliminating dead-on-fill blocks, FLEXII helps dynamic cache resizing mechanisms further reduce their energy consumption.
