摘　　要：功耗问题已经成为制约电子系统发展的重要因素.功耗是由硬件在运行软件时产生的,软件的数据存取和指令执行都会使硬件产生功耗.编译器可以通过适当的调度优化,改变软件在硬件上的运行轨迹,使得硬件执行某一个程序时的功耗变小.本文从如何对软件的功耗进行评估和如何实现低功耗的编译两大方面对低功耗编译的相关研究进行了广泛介绍,着重评述了专门的低功耗编译技术.最后对当前低功耗编译存在的问题做了分析,给出了对于低功耗编译新方向的预测.Power/energy has been an important constraint for development of electronic system. Power/energy is consumed by hardware when software runs on it, for accessing data and executing instructions of software can both make hardware consume power/energy. Compiler can change the behavior of software running on the hardware by optimized scheduling, such that the power/energy consumption of certain program decreases. This paper comprehensively reviews low power/energy compilation technology related researches from two aspects, how to evaluate software power/energy consumption and how to achieve low power/energy by means of compilation technologies. In the end, we analysis the existing problems in current researches on low power/energy compilation Technology, and predicate some new directions on the low power/energy compilation technology.
