摘要

对多无线电移动平台的详细功率分析突出了计算、存储和通信子系统之间的复杂权衡。特定的移动设备，不包括LCD或其他车载显示器，可以用作音频或视频媒体文件的源或安全数据传输的源/接收器。该设备的一个版本已经增强了细粒度功率监测功能，并用于获得各个子系统功耗的详细测量。对这些测量结果的分析揭示了不同应用程序的功耗特征，从而为系统设计人员提供了关于潜在优化领域的提示。具体来说，这项工作对比了系统支持的各种无线技术的功率效率。

Experience with a low power wireless mobile computing platform

A detailed power analysis of a multi-radio mobile platform highlights the complex tradeoffs between the computation, storage, and communication subsystems. The particular mobile device, which does not include an LCD or other on-board display, can be used as a source for audio or video media files or a source/sink for secure data transfers. A version of the device has been augmented with fine-grained power monitoring capability and used to obtain detailed measurements of power dissipation in the various subsystems. Analysis of these measurements sheds light on the power consumption characteristics of different applications, thereby providing hints to system designers about potential areas for optimization. Specifically, this work contrasts the power efficiency of the various wireless technologies supported by the system.
