摘　　要：嵌入式产品体积的缩小和更长使用时间的要求,使嵌入式系统对功耗管理的要求越来越高。给出了一种实时功耗管理算法,对其功耗管理效果进行了研究和分析。详细描述了ucLinux中的功耗管理机制,并结合嵌入式系统的特点,对其进行了研究和改进。以此基础,在ucLinux中实现了动态功耗管理算法,给出了具体的功能实现描述,并验证了其效果。结果表明,这种方法起到了较好的功耗管理效果,实现了对嵌入式系统外设有效的功耗管理。With the reduction of the embedded product and need of the more service time, embedded system makes more and more demands on the power management. An online power management algorithm is presented, and the effect is researched. Described the mechanism ofucLinux power management in detail, and improved it according to the characteristic of embedded system. An algorithm of dynamic power management is implemented, and the method is given in detail. The effect of power management is validated. The result proved that this method had a good effect on the power management of the peripheral equipment.
