| Research Abstract |
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.
