摘　　要：文章提出了一种自适应的动态功耗管理系统,能够根据硬件监测系统对So C各资源使用情况的反馈,按照事先配置的低功耗策略,调整片上系统各模块工作状态,在满足性能需求的情况下达到降低功耗的目的。该功耗动态管理系统能够独立于具体应用,由硬件自动完成对系统芯片工作状态的调整,不仅能够针对不同的应用进行工作状态调整,在同一应用的不同阶段也可以根据资源占用情况来调节系统工作状态,具有很高的灵活性和实时性。In this paper, we introduce a self-aware dynamic power management system, which is used to decrease the power consumption of the So C system without performance cost by adjusting the working state of the So C system dynamically. This dynamical working state adjustment is performed by the hardware automatically according to the feedback of the monitor module and the adjustment strategy configured by software in advance. This dynamic power management system is able to adjust the working state not only between different applications, but also between different stages in the same application if the occupancy of resources is changed. The adjustment is flexible and real-time.
