摘　　要：研究嵌入式系统的节能问题。针对工业控制中嵌入式系统的应用广泛,应用的环境复杂,大中小型的系统功耗不断的提高,急需降低系统的能量消耗的问题。为了有效地降低功耗,提出了基于平衡点算法的降低嵌入式系统能耗的方法。利用工业控制系统工作的时候频率调节和工作电压测量技术,计算出系统功耗最低的时候,电压和频率的平衡点,使得系统在平衡点状态下工作。进而达到降低能耗的目的。实验表明。利用调节算法,能够有效降低以ARM7为主的CMOS工业控制中嵌入式系统的功耗,对工业系统取得较好的效果,为设计提供了依据。Researching on the problem of energy embedded systems.The range of applications for embedded systems have become more and more wide.the application environments have become more and more complex,and the system power consumption has been too high,which urgently needs reducing system power consumption.A balance algorithm was proposed.The regulating technique of working load and voltage is used to dynamically change the operating power of the embedded systems,thus to reduce the energy consumption.Experiments show that the balance algorithm can reduce the power consumption of ARM7 embedded systems and achieve satisfactory results.
