US09436268B2 System power control using a power supply to provide voltage to subsystems in which a subsystem determines its operating state based on the voltage received by the subsystem 有权
使用电源对基于子系统接收的电压确定子系统的运行状态的子系统提供电压的系统功率控制

System power control using a power supply to provide voltage to subsystems in which a subsystem determines its operating state based on the voltage received by the subsystem
Abstract:
A power control unit 16 controls the power consumed by a system 10 having a plurality of electrical power consumption states including an active state and at least one power saving state. The system comprises a plurality of subsystems 12 each having a plurality of subsystem power states including an active state and at least one power saving state. The electrical power consumption states of the system correspond to respective different configurations of subsystem power states of the subsystems and the power control unit is arranged for signal interface with the subsystems and a power supply unit 14 of the system for controlling the subsystem power states of each of the subsystems and the power supplied to each of the subsystems by the power supply unit dependent on the required power consumption state of the system.
Abstract(Chinese):

功率控制单元16控制具有包括活动状态和至少一个省电状态的多个电力消耗状态的系统10所消耗的功率。 该系统包括多个子系统12，每个子系统具有包括活动状态和至少一个省电状态的多个子系统功率状态。 系统的电力消耗状态对应于子系统的子系统功率状态的相应不同配置，并且功率控制单元被布置用于与子系统的信号接口以及用于控制系统的子系统功率状态的系统的电源单元14 并且由供电单元依赖于系统的所需功耗状态而提供给每个子系统的功率。
