| 摘 要： | 当代CMP处理器通常采用基于LRU替换策略或其近似算法的共享最后一级Cache设计.然而,随着LLC容量和相联度的增长,LRU和理论最优替换算法之间的性能差距日趋增大.为此已提出多种Cache管理策略来解决这一问题,但是它们多数仅针对单一的内存访问类型,且对Cache访问的频率信息关注较少,因而性能提升具有很大的局限性... |

| Abstract: | Modern CMP processors usually employ shared last-level cache(LLC) based on LRU replacement policy and its approximations.However,as the LLC grows in capacity and associativity,the performance gap between the LRU and the theoretical optimal replacement algorithms has widened.Various alternative cache management technologies have been proposed to resolve this problem,but they only cover a single type of memory access behavior,and exploit little frequency information of cache accesses,thus have limited perform... |
