1这项工作得到了根据合同＃1010-2004-0098摘要 - 能量和性能的收益，这是设计嵌入式系统的两个最重要的参数。嵌入式应用程序的能量和性能剖面工具主要基于硬件仪器，该仪器在执行嵌入式应用程序过程中测量当前样品。通过使用EPRO提供的性能监控单元，在嵌入式应用程序中，在嵌入式应用程序中进行了几乎没有侧面效果的应用程序。信号处理应用分别为5.4％和4.4％。
1 This work was supported by Electronics and Telecommunications Research Institute under contract # 1010-2004-0098 Abstract – Energy and performance are two of the most important parameters in designing embedded systems. In this paper, we describe the architecture and implementation of ePRO, a tool for energy and performance profiler for embedded applications. Energy profiling is mainly based on the hardware instrumentation which measures current samples during execution of embedded applications with the support of a periodic kernel module. Performance profiling is done with little side effect to embedded applications by using a performance monitoring unit which is provided in the architectural level. Using ePRO, we could improve the energy consumption and the performance of a digital signal processing application by 5.4% and 4.4%, respectively.
