| 摘 要： | 对多种末级高速缓存插入策略进行分析, 并在动态插入策略DIP的基础上提出一种分阶段自我调整的动态插入策略, 用于消除局部性差数据访问末级高速缓存造成的不良影响。实验结果表明, 与现有LRU替换算法相比, 此方法将末级高速缓存的MPKI平均降低了7.07%, 即使与动态插入策略DIP相比, 此方法也获得进一步的性能提升, 末级高速缓存MPKI平均降低了4.36%。

| Abstract: | The authors analyze multiple last level cache insertion policies and propose a phase-based adaptive dynamic insertion policy based on DIP (dynamic insertion policy) for eliminating the harmful effect of non-reusable data. The experiment result shows that in comparison with LRU (least recently used), the proposed approach can reduce the last level cache misses per thousand instructions, MPKI, 7.07% on average; even in comparison with DIP policy, the new approach can also improve last level cache performance in further, and average MPKI is reduced by 4.36%. |
