Abstract

Today more than ever, energy and power distribution on heterogeneous multicore platforms have immense influence on hardware and software architectures because of general tendencies towards energy efficient solutions. This paper provides an insight into the overall energy and power distribution on an ultra-low power heterogeneous multicore platform designed for hearing aids, especially focusing on energy dissipation that is caused by instructions execution. This research has been conducted in order to provide instruction set energy profile that could be used during instructions selection for both developer and compiler. Also, information about instructions energy consumption could be used for power profiling of entire firmware solutions, therefore providing valuable feedback to developers. Experiments have been conducted using customized Eclipse based Integrated Development Environment (IDE), the toolchain (Compiler, Assembler, Linker) developed for that particular target platform, and true RMS multimeter used for measurements. The outcome of the experiments has unequivocally confirmed that the obtained instruction set energy profile provides reliable information that could be used in various ways.

异构多核平台上的指令能耗

由于节能解决方案的普遍趋势，异构多核平台上的能源和功率分配对硬件和软件架构的影响比以往任何时候都要大。本文介绍了一种用于助听器的超低功耗异构多核平台的整体能量和功率分布，特别关注指令执行引起的能量耗散。本研究旨在为开发人员和编译器的指令选择提供指令集能量分布图。此外，有关指令能耗的信息可用于整个固件解决方案的功耗分析，从而为开发人员提供有价值的反馈。实验是使用定制的基于Eclipse的集成开发环境(IDE)、为特定目标平台开发的工具链(编译器、汇编器、链接器)和用于测量的真实RMS万用表进行的。实验结果明确地证实了所获得的指令集能量分布图提供了可靠的信息，可用于各种方式。
