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.
