Abstract: Methods of managing wasted active power of processors in computer systems and other electronic devices are disclosed. In one aspect, a method may include counting a number of times that a processor has performed an instruction loop. Then, a determination may be made whether the number of times that the processor has performed the loop is greater than one or more thresholds or other given values. Next, a limit may be imposed on the power of the processor if the number of times that the processor has performed the loop is greater than at least one of the thresholds or given values. Logic to perform such methods is also disclosed, as are systems suitable for incorporating such logic.

Abstract: A method and apparatus for self-refresh in a display device is described. In an embodiment, a system display has a display screen that includes a pixel value storage component. The system display is coupled with a graphics control module via a display bus and enables a self-refresh mode based on a first indication from the graphics control module. The self-refresh mode includes refreshing pixel values stored within the pixel value storage component. The self-refresh rate is not greater than, a refresh rate provided by the graphics control module.
