摘要
低能耗在现代工业中受到特别的关注,较低的能量耗费正成为嵌入式系统,特别是便携式设备所要解决和实现的重点目标之一。仅依靠硬件技术,实现节能的潜力正在逐渐减小。使用软件技术优化系统能量正得到更多的关注。从操作系统资源管理的角度,分析了嵌入式操作系统节能原理,探讨操作系统的节能策略;从软件的设计模式、编译优化等方面出发,研究了嵌入式应用软件的节能原理以及相应的节能方法。
Special attention is paied to low power consumption in modern industry,low power is one of the main goals to be studied, solved and realized for embedded system,especially for the portable devices. Hardware ean hardly make more eontribution on energy saving. Many research activities have targeted at reducing energy consumption of embedded systems through software optimizations. From the perspective of power management, some principles about low power consumption in embe dded OS are analyzed, from the directions of model design and compiler otimization, many principles about low power consumption in embedded application software are researched and the corresponding strategies and methods are given.
