概要 A number of techniques to reduce the cache leakage energy have so far been proposed. However, the low-leakage caches cause performance degradation. In order to solve this performance issue, we propose... a new cache management technique. In this approach, a small number of cache lines which are frequently accessed in sleep mode are forced to stay in always-active mode. In this mode, transiting to the sleep mode is prohibited. In our evaluation, this approach can eliminate almost all performance overhead compared to conventional low-leakage cache without affecting the energy efficiency.続きを見る
