Abstract

A power consumption measurement framework for embedded processing systems is presented in this work. Given an assembly or machine level program as input to this setup, the energy consumption of the specific program in the specific processing systems may be estimated. The instruction level power models are derived based on the power supply current measurement technique. The instantaneous variations of the power supply current provide the appropriate information for the accurate estimation of the power consumption at different operating situations of the processor (core) and of the overall processing system as well (consumption of peripheral units). The proposed instantaneous current measuring approach, along with the execution of special test programs for analysis of inter-instruction effects provides a clear insight into the power behavior of embedded processing systems.

指令级功耗估计嵌入式处理器低功耗应用

本文提出了一种嵌入式处理系统的功耗测量框架。给定一个装配或机器级程序作为该设置的输入，可以估计特定处理系统中特定程序的能耗。基于电源电流测量技术，推导了指令级功率模型。电源电流的瞬时变化为准确估计处理器(核心)和整个处理系统在不同操作情况下的功耗以及(外围设备的功耗)提供了适当的信息。所提出的瞬时电流测量方法，以及用于分析指令间效应的特殊测试程序的执行，为嵌入式处理系统的电源行为提供了清晰的见解。
