中文摘要
在芯片多处理器(CMP)体系结构中,多个内核通常共享内存层次结构中的资源,包括最后一级缓存、内存总线和DRAM内存组。通过构建资源冲突下的CPU功耗模型,推导出CPU总功耗最小的条件,并提出了一种新的动态优化方法,通过DVFS对多个共享资源的协同访问控制使CPU总功耗最小。
英文摘要
In a chip multiprocessor (CMP) architecture, multiple cores usually share resources in the memory hierarchy including the last-level cache, the memory bus, and the DRAM memory banks. We derive the condition where the total CPU power consumption becomes minimum by constructing a power consumption model under resource conflicts, and propose a novel dynamic optimization method to minimize the power consumption by a cooperative access control to multiple shared resource with DVFS.
