摘要

基于阶段的调优通过为应用程序执行阶段配置系统参数来增加优化潜力。先前的工作提出了相位距离映射(PDM),它依赖于对执行应用程序进行广泛的先验分析,利用相位之间的相关性来动态估计最佳配置。我们提出了DynaPDM,一种新的动态相位距离映射方法,它消除了先验的设计工作,动态分析相位,并确定最佳配置,产生平均能源延迟产品节省28%-比pdm改进8%-配置在最优的1%以内。

Exploiting dynamic phase distance mapping for phase-based tuning of embedded systems
Phase-based tuning increases optimization potential by configuring system parameters for application execution phases. Previous work proposed phase distance mapping (PDM), which relied on extensive a priori analysis of executing applications to dynamically estimate the best configuration using the correlation between phases. We propose DynaPDM, a new dynamic phase distance mapping methodology that eliminates a priori designer effort, dynamically analyzes phases, and determines the best configurations, yielding average energy delay product savings of 28%-an 8% improvement on PDM-and configurations within 1% of the optimal.
