【摘要】：面向代码的软件能耗优化从程序设计和编码角度优化软件系统的能耗,能够很好地弥补面向硬件和面向资源的能耗优化方法过多依赖硬件环境、普适性较差、粒度过大,且难以在软件开发过程中应用等缺点.该文综述了近年来面向代码软件能耗优化领域的主要研究成果,总结了能耗优化的基本方法和技术层次以及面向代码的软件能耗优化基本思路;随后从面向代码的软件能耗估算方法和优化方法两个方面对现有工作加以梳理,逐一介绍了相关优化工具.该文提出了若干进一步研究的问题.首先,该文重定义面向代码的软件能耗评估模型和方法应该满足的特性,并提出代码的运行时能耗(Runtime Energy Consumption)和视在能耗(Apparent Energy Consumption)的概念;其次,该文认为现有面向代码的能耗优化技术过于具体,或针对具体的代码,或针对具体的功能,缺乏抽象层次的优化技术,缺乏算法层面的能耗优化方法,且没有充分考虑编程语言特征,尤其是面向对象语言特征;最后,该文提出算法能耗复杂度这一新观点,指出仍然存在的问题和可能的解决办法.
[Abstract]:Code-oriented software energy consumption optimization optimizes the energy consumption of software systems from the point of program design and coding, which can make up for hardware and resource-oriented energy consumption optimization methods that rely too much on hardware environment, poor universality and too large granularity. And it is difficult to be applied in software development. This paper summarizes the main research achievements in the field of code-oriented software energy consumption optimization in recent years, summarizes the basic methods and technical levels of energy consumption optimization and the basic ideas of code-oriented software energy consumption optimization. Then the existing work is combed from two aspects of code oriented software energy consumption estimation method and optimization method, and the related optimization tools are introduced one by one. This paper puts forward some problems for further study. First of all, this paper redefines the characteristics that should be satisfied by the software energy consumption evaluation model and method oriented to code, and puts forward the concepts of Runtime Energy consumption and Apparent Energy consumption. This paper thinks that the existing code-oriented energy consumption optimization technology is too specific, or for specific code, or for specific functions, lack of abstract level of optimization technology, lack of algorithmic level of energy optimization methods. The programming language features, especially the object-oriented language features, are not fully considered. Finally, this paper puts forward a new viewpoint of algorithm energy consumption complexity, and points out the existing problems and possible solutions.
