摘　　要：低功耗的设计已经成为嵌入式系统设计中一个非常重要的方面,而动态电压调度算法DVS又被认为是降低功耗的一种有效手段。分析了已有的基于电池剩余电量的DVS调度算法局限性,通过实验对非周期性电流负载对应的电池单元行为进行建模,设计了一种新的低能耗调度算法。实验证明该算法能很好满足复杂的具有非周期性任务特点的嵌入式实时系统的性能与低功耗要求。Low power consumption design has become very important in the embedded system design. Furthemore,DVS is considered to be an efficient method to save energy. This paper researched the disadvantage of DVS arithmetic based battery residual, then builded a model for unique discharge characteristics due to non-periodic tasks by experiments,and designed a new arithmetic, which significantly reduces power to extend the battery lifetime and upgrades QoS for embedded real-time system effectively.
