动态电源管理 (DPM) 是一种动态重新配置系统的设计方法，以最少数量的活动组件或此类组件上的最小负载提供所需的服务和性能水平。 DPM 包含一组技术，通过在系统组件空闲（或部分未利用）时有选择地关闭（或降低其性能）来实现节能计算。在本文中，我们调查了几种系统级动态电源管理方法。我们首先描述系统如何使用电源管理组件以及动态重新配置调用的使用如何影响整体功耗。然后，我们分析电子系统中的 DPM 实施问题，并调查最近在标准化硬件/软件接口以实现硬件组件的软件控制电源管理方面的举措。
Dynamic power management (DPM) is a design methodology for dynamically reconfiguring systems to provide the requested services and performance levels with a minimum number of active components or a minimum load on such components. DPM encompasses a set of techniques that achieves energy-efficient computation by selectively turning off (or reducing the performance of) system components when they are idle (or partially unexploited).In this paper, we survey several approaches to system-level dynamic power management. We first describe how systems employ power-manageable components and how the use of dynamic reconfiguration call impact the overall power consumption. We then analyze DPM implementation issues in electronic systems, and we survey recent initiatives in standardizing the hardware/software interface to enable software-controlled power management of hardware components.
