Abstract

In order to achieve a low energy execution for any multimedia applications (MMAs) on a vector processing mechanism (VPM), the number of parallel arithmetic pipelines and the number of cache ports of VPM must be properly configured for each MMAs. Therefore, this paper proposes an energy optimization method for VPMs (EOM-VP), which finds the lowest energy configuration by using the greedy searching method and an analytical model. As the evaluation results suggest, EOM-VP could find the lowest or the second lowest energy configuration for all the benchmark programs in the evaluation.
矢量加工机构的能量优化方法
为了实现基于矢量处理机制(vector processing mechanism, VPM)的多媒体应用程序的低能耗执行,必须对每个多媒体应用程序的并行运算管道数量和矢量处理机制的缓存端口数量进行合理配置。为此,本文提出了一种vpm的能量优化方法(EOM-VP),该方法利用贪婪搜索法和解析模型寻找最低能量配置。评价结果表明,EOM-VP可以找到评价中所有基准方案的最低或次低能量配置。
