    • An apparatus and method for power management of a display system. A display controller couples to a memory storage device. A frame buffer in the memory storage device is filled with frames of information for display on a display device. The frames of information transfer to a display buffer in the display controller. The display controller transmits the frames of information from the display buffer to the display device. When frame information is not being transferred to the display controller, the display controller and the memory storage device may separately enter a power saving state. In power saving state, the display controller may continue to transmit frame information to the display device; however, power and a clock signal to components of display controller may be limited. When the display buffer is almost empty, the display controller exits power saving state to fill the display buffer.

    • An apparatus and method for controlling standby mode in an electronic device. In standby mode, power and clock signals are reduced or stopped to conserve power. The apparatus includes an initiator module coupled to a power and clock control module (PCCM). When the initiator module meets conditions for standby mode, the initiator module sends a standby signal to the PCCM and does not interact with other initiator, target, or interconnect modules. When the PCCM communicates a wait signal, the initiator module enters standby mode. When the initiator module detects a wakeup event, the standby signal is deactivated. In this state, the initiator module may process information but may not interact with other modules. When the PCCM deactivates the wait signal and returns power and clock signal to steady state levels, initiator module may resume normal operation.
    • 一种用于控制电子设备中的待机模式的装置和方法。 在待机模式下,电源和时钟信号被减少或停止以节省电力。 该装置包括耦合到电源和时钟控制模块(PCCM)的启动器模块。 当启动器模块满足待机模式条件时,启动器模块向PCCM发送备用信号,不与其他启动器,目标或互连模块进行交互。 当PCCM通信等待信号时,启动器模块进入待机模式。 当启动器模块检测到唤醒事件时,待机信号被禁用。 在这种状态下,启动器模块可以处理信息,但是可能不与其他模块进行交互。 当PCCM关闭等待信号并将电源和时钟信号恢复到稳定状态时,启动器模块可以恢复正常工作。

    • An apparatus and method for controlling idle mode in an electronic device. In idle mode, power and clock signals are reduced or stopped to conserve power. The apparatus includes a target module coupled to a power and clock control module (PCCM). The PCCM sends an idleack signal to the target module when at least one initiator module within the device is in a power saving mode. When the target module satisfies conditions for idle mode, the target module sends an idleack signal to the PCCM and enters idle mode. In this state, the target module may process information but may not interact with other modules. When the target module detects a wakeup event, a wakeup signal is sent to the PCCM. When the PCCM returns the normal power and clock signal to the target module, the target module may resume normal operation.
    • 一种用于控制电子设备中的空闲模式的装置和方法。 在空闲模式下,电源和时钟信号被减少或停止以节省电力。 该装置包括耦合到电源和时钟控制模块(PCCM)的目标模块。 当设备中的至少一个启动器模块处于省电模式时,PCCM向目标模块发送空闲信号。 当目标模块满足空闲模式的条件时,目标模块向PCCM发送空闲信号并进入空闲模式。 在这种状态下,目标模块可以处理信息,但可能不与其他模块交互。 当目标模块检测到唤醒事件时,会向PCCM发送唤醒信号。 当PCCM向目标模块返回正常的电源和时钟信号时,目标模块可以恢复正常运行。
