Abstract

Cache memories are the bottle-necks that limit the performance of the processors. In this paper, we present a heuristic algorithm for tuning the level-1 cache. The tuning method searches for the most energy efficient cache configuration under application performance requirement. By simulations we show that the proposed heuristic tuning algorithm is able to find the optimal or near optimal configurations. An algorithm for reducing the number of searched configurations is also proposed.

具有性能限制的高能效缓存定时
高速缓存存储器是限制处理器性能的瓶颈。在本文中,我们提出了一种用于调优一级缓存的启发式算法。调优方法在应用程序性能要求下搜索最节能的缓存配置。仿真结果表明,所提出的启发式优化算法能够找到最优或接近最优的配置。提出了一种减少搜索配置数的算法。
