开发用于多处理器片上系统（MPSoC）的能量感知软件是一项困难的任务，这需要了解多个异构设备（核、存储器、总线等）之间的功耗分布。在这项工作中，我们分析了一个完整的MPSoC平台的功耗的功耗故障，在几个应用程序的工作负载和操作条件。我们利用完整的系统仿真平台，为所有关键硬件模块提供精确的功耗模型。我们的分析表明，高速缓存和系统互连占主导地位的电源故障，指出如何软件本地性是有意义的，不仅性能，而且能源优化。
Developing energy-aware software for multiprocessor systems-on-chip (MPSoCs) is a difficult task, which requires the knowledge of the distribution of the power consumption among several heterogeneous devices (cores, memories, busses, etc.). In this work we analyze the power breakdowns of power consumption for a complete MPSoC platform, under several application workloads and operating conditions. We leverage a complete-system simulation platform with accurate power models for all key hardware modules. Our analysis shows that caches and system interconnect dominate in the power breakdown, pointing out how software locality is meaningful not only for performance but also for energy optimization.
