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%.
