| 摘 要： | 文章从软件低功耗优化角度,结合IXP2400网络处理器中XScalecore处理器体系结构的低功耗技术特点,在SimWattch模拟平台上,就频率动态调整和程序设计语言不同结构成分对应用程序运行功耗的影响进行了模拟和分析,通过对一组Banchmark程序的模拟,结果表明在编译系统、操作系统或应用程序设计中采用这些低功耗优化技术设计可降低至少23%以上的运行功耗。

| Abstract: | From the software aspect for low power optimization,the architecture of XScale core in IXP2400network pro-cessor is simulated on SimWattch.The effect of dynamic scalable frequency and components of programming language on the power consumption of running an application is analyzed in this paper.The results of simulating a set of benchmark programs demonstrates that the power consumption can be decreased at least above23%by using these technologies for low power in the design of the compiler,operating system or application program. |
