06938176 is referenced by 126 patents and cites 11 patents.

A graphics processing device implementing a set of techniques for power management, preferably at both a subsystem level and a device level, and preferably including peak power management, a system including a graphics processing device that implements such a set of techniques for power management, and the power management methods performed by such a device or system. In preferred embodiments, the device includes at least two subsystems and hardware mechanisms that automatically seek the lowest power state for the device that does not impact performance of the device or of a system that includes the device. Preferably, the device includes a control unit operable in any selected one of multiple power management modes, and system software can intervene to cause the control unit to operate in any of these modes.

Title
Method and apparatus for power management of graphics processors and subsystems that allow the subsystems to respond to accesses when subsystems are idle
