商用处理器上针对能耗优化的DVFS调节机制
Energy Consumption Optimization DVFS Mechanism for Commercial Processors
摘要
Abstract
Aiming at the impact of Dynamic Voltage Frequency Scaling(DVFS) on program's performance and power consumption,based on interval division,this paper uses existing performance monitoring unit provided by commercial processor,it proposes a performance prediction model which takes the relation between memory access latency and frequency into account.It presents an energy-optimized DVFS(eDVFS) control policy that aims to minimize energy consumption.Experimental results show that eDVFS can get 23% at most and 6.85% on average in energy saving compared with Linux 'ondemand' adjusting policy.关键词
