摘 要: 在电池供电的实时系统中,需要考虑到两个约束:一个是实时系统中任务的截至时间,另一个就是能量问题。在系统设计的过程中,从物理层、体系结构层、系统层到网络层的各个层次上都可以进行低功耗技术设计。在分析了为什么在系统层上进行低功耗技术之后,又给出了目前系统层上一种主要的技术机制,对这种机制在实时系统中进行任务调度的具体方法进行了概括和总结。 There are two constraints need to addressed in battery-powered real-time systems, one is the deadline of the task in real-time systems and the other is energy issue. During the process of the system designing, there is low power dissipation method at all levels from physical level, architecture level, system level to network level. After analyzing why to do low power dissipation techniques at system-level, the main technique mechanisms at the system-level are given, and the specific method to do tasks scheduling is generalized using this mechanism in real-time systems.
