嵌入式系统动态电源管理算法研究

嵌入式系统的能耗问题已经成为嵌入式系统设计中的难点与热点。动态电源管理策略、内存管理机制、总线编码技术和硬件设计等方法被用来降低能耗。比较而言，动态电源 管理是最直接、最有效的方法。本文先从理论上分析了能耗问题的特点，然后研究了目前比较流行的几种动态电源管理算法，并对试验结果进行了比较和理论分析。

A Study of the Dynamic Power Management in Embedded Systems

The problem of power consumption in embedded systems has become the focus and difficulty in embedded system design. The methods of dynamic power management, memory management mechanism, bus code technology and hardware design are used to reduce power consumption.Comparison shows that dynamic power management is the most direct and effective one.This paper analyzes the traits of power consumption and studies several algorithms of dynamic power management.Finally it compares the results of the experiment and makes a theoretical analysis.
