Abstract: An accelerated graphics processing subsystem that significantly increases the processing speed of computer graphics commands. The preferred embodiment of this invention presents a first-of-its-kind graphics processing subsystem that combines the processing power of multiple, off-the-shelf, video cards, each one having one or more graphic processor units. The video cards can be used without substantial modification. Under the preferred embodiment, each video card processes instructions for drawing a predetermined portion of the screen which is displayed to the user through a monitor or other visual output device. The invention harnesses the power of multiple video cards without suffering from the high bandwidth constraints affecting prior attempts at parallel graphics processing subsystems.

Abstract: An accelerated graphics processing subsystem combines the processing power of multiple graphics processing units (GPUs) or video cards. Video processing by the multiple video cards is organized by time division such that each video card is responsible for video data processing during a different time period. For example, two video cards may take turns, with the first video card controlling a display for a certain time period and the second video sequentially assuming video processing duties for a subsequent period. In this way, as one video card is managing the display in one time period, the second video card is processing video data for the for the next time period, thereby allowing extensive processing of the video data before the start of the next time period. The present invention may further incorporate load balancing such that the duration of the processing time periods for each of the video cards is dynamically modified to maximize composite video processing.
