摘 要: 便携系统越来越广泛的应用使得电池使用问题日益突出。对能量敏感实时系统的能量管理进行了分析和探讨,通过对任务执行过程中的电压进行调整以减少实时任务的能量消耗,给出了能量敏感实时系统的静态能量管理和动态能量管理的分析方法,并提出了具有截止时间限制的实时任务减少能量消耗的调度机制。 Battery usage becomes an outstanding problem because of the vast application of portable systems. This paper gives a detailed analysis and discussion about power management in energy-aware real-time systems. The energy consumption in real-time task execution process is reduced by using dynamic voltage scaling mechanism. It also gives an analysis method of static power management and dynamic power management in real-time systems, and gives a scheduling mechanism about the real- time tasks which have deadline constraints to reduce its energy consumption.
