    • A power management system and interface providing a flexible and uniform protocol for controlling power management within a computer system including various software layers and add-in components. Clients (registered system elements) requiring power management notification and control become registered (via an associated software component) with a power management coordinator (PMC). The PMC provides information routing functions and address translations to facilitate communication (including power consumption information) between clients at registered identifiers. A programmable power policy manager allows a user to define a performance/economy setting for the system that is communicated to all registered devices so that dwell and decay times are appropriately set by the device. A programmable event sequencer maintains an event notification sequence and control sequence for power events. A programmable power budgeter maintains and allocates power on a request basis for system elements. A programmable thermal budgeter maintains and allocates energy based on thermal considerations. A BIOS interlace couples for communication between an APM BIOS (if present) to send commands and poll for and receive event notification. Registered extensions may be used to provide alternate functionality for the sequencer, the power policy manager, and the thermal and power budgeters. The PMC provides for communication of power status, events, and other information between registered devices and allows registered software applications to originate power events. Other extensions may register to enhance power management.
    • 一种电源管理系统和接口,其提供用于在包括各种软件层和附加组件的计算机系统内控制电源管理的灵活和统一的协议。 要求电源管理通知和控制的客户端(注册系统元件)通过电源管理协调器(PMC)注册(通过相关联的软件组件)。 PMC提供信息路由功能和地址转换,以促进在注册的标识符之间的客户端之间的通信(包括功耗信息)。 可编程电源策略管理器允许用户定义传送到所有注册设备的系统的性能/经济性设置,以便设备适当地设置驻留时间和衰减时间。 可编程事件定序器维护电力事件的事件通知序列和控制顺序。 可编程功率预算器根据系统元件的请求维护和分配功率。 可编程热预算员基于热考虑维护和分配能量。 BIOS交换耦合用于APM BIOS(如果存在)之间的通信以发送命令并轮询并接收事件通知。 注册扩展可用于为定序器,电源策略管理器,热和功率预算员提供备用功能。 PMC提供注册设备之间的电源状态,事件和其他信息的通信,并允许注册的软件应用程序发起电源事件。 其他扩展可以注册以增强电源管理。
