    摘要: In a power management scheme for a power-consuming (e.g. electronic) device, one of multiple predefined operating parameter sets is selected. Each of the sets comprises multiple operating parameter values for the device. Examples of operating parameters include clock frequency or voltage for example. The selection may be responsive to the detection of an event which warrants a change in a current power consumption state of the device. Any operating parameter value in the selected set that would prevent the device from meeting current operating demands is modified to a new value. The new value may be taken from another operating parameter set. The modified set of parameters is applied to the device in order to change the current power consumption state of the device.

    摘要: A variable clock control information generator receives graphics engine activity data relating to the operating level of a graphics engine, and memory activity data relating to an activity level of memory. In response, the variable clock control information generator produces graphics engine clock control information and memory clock control information with respect to each other, such that a relative difference between the graphics engine activity data and the memory activity data is within balance threshold data. Accordingly, the variable clock control information generator adapts to the varying levels of graphics engine activity and memory activity and adjusts the frequency of the graphics engine clock signal and the frequency of the memory clock signal to achieve a balanced relative activity level.

    摘要: A method and apparatus controls power management of a graphics processing core when multiple virtual machines are allocated to the graphics processing core on a much finer-grain level than conventional systems. In one example, the method and apparatus processes a plurality of virtual machine power control setting requests to determine a power control request for a power management unit of a graphics processing core. The method and apparatus then controls power levels of the graphics processing core with the power management unit based on the determined power control request.

    摘要: In devices in which display data is read from a memory for display, display underflow in a processing block is alleviated by controlling a clock frequency driving the processing block. Stages of the processing block send underflow detection signals to underflow prevention logic. The underflow prevention logic controls the frequencies of clock signals generated by a clock generator to alleviate the underflow condition.
