【摘要】：从移动终端的出现开始，移动终端能量消耗的管理就一直是个具有挑战性的问题。尽管受到自身携带电池限制，移动终端的续航能力仍然可以得到优化。低功耗芯片的设计和硬件能量的管理技术已经可以得到更高能效的终端系统。除此以外，从操作系统和应用软件等系统级层面，在能量效率管理上还有很大的提升空间。本文的主要内容就是从更高的系统层面来度量能量效率问题。我们通过使用一个基于安卓平台的能效分析工具，将终端的能量的消耗转换为可视化的图形，统计分析能量消耗较大的程序段来帮助开发人员完成具有高能效的软件。实验结果表明，通过改变应用程序执行的方式可以显著提高电池的续航时间。在不同的操作系统平台上，业务的服务质量的适度下降、无线连接方式的改变，可以降低应用程序的能量消耗约94%。进一步研究结果还表明，能量自适应是对现有硬件能量管理技术的补充。实验研究表明，，基于能量效率目标导向设计的应用软件可以延长移动终端的电池的续航时间约30%。
[Abstract]:Since the advent of mobile terminals, the management of mobile terminal energy consumption has been a challenging issue. The design of low-power chips and hardware energy management techniques have enabled more energy-efficient terminal systems. In addition, at the system level, such as operating systems and application software, There is still a lot of room for improvement in energy efficiency management. The main content of this paper is to measure energy efficiency at a higher system level. We use an energy efficiency analysis tool based on Android platform to convert terminal energy consumption into visual graphics. Statistical analysis of program segments that consume more energy to help developers complete energy-efficient software. Experimental results show that, The battery life can be significantly improved by changing the way the application executes. On different operating system platforms, the service quality of service is reduced moderately, and the mode of wireless connection is changed. The energy consumption of the application can be reduced by about 94. Further research results also show that energy adaptation is a supplement to the existing hardware energy management technology. Application software based on energy efficiency goal-oriented design can extend battery life of mobile terminal by about 30%.
