  • Patent number: 8839006
    Abstract: Power management systems and methods that facilitate efficient and effective power conservation are presented. In one embodiment a power management method comprises: performing an initiation metric determination process, and adjusting operations of a logic component based on said threshold value. In one exemplary implementation, the initiation metric determination process includes monitoring activity of a logic component, and establishing a power conservation initiation threshold value. The initiation metric determination process can include performing a system architecture characteristic analysis in which a system architecture power-consumption break-even time (BE) is determined for the system. The initiation metric determination process can also include performing a system utilization analysis process is performed in which idle period durations detected during said monitoring are sorted into a variety of different length intervals and analyzed accordingly.

  • Publication number: 20130169656
    Abstract: Embodiments of the present invention may be directed to a graphics system of a computer system. The system may include a frame buffer having a number of partitions respectively mapped to a number of discrete memory devices and a dedicated copy buffer operable to store new image frames, mapped to a first memory device. The first memory device corresponds to a first partition of the number of partitions. The system may also include a loader circuit coupled between the frame buffer and the dedicated copy buffer, operable to copy new image frames from the frame buffer to the dedicated copy buffer. The system may also include a clocked output coupled to receive an image frame from the dedicated copy buffer and operable to drive a display device therewith. The system may enter a low power state wherein a number of the discrete memory devices are powered off.
