Abstract:
1. A method for processing an ordered sequence of images for display using a display device comprising: operating a plurality of graphics devices each capable of processing images by performing rendering operations to generate pixel data, including at least one first graphics device and at least one second graphics device, each graphics device including an internal switching feature configurable to select between outputting pixel data generated by the graphics device and receiving and forwarding pixel data of another graphics device; using the plurality of graphics devices to process the ordered sequence of images, wherein the at least one first graphics device processes certain ones of the ordered sequence of images, including a first image, and the at least one second graphics device processes certain other ones of the ordered sequence of images, including a second image, wherein the first image precedes the second image in the ordered sequence of images, wherein the at least one first graphics device is part of a first graphics device group responsible for processing the first image, wherein each graphics device in the first graphics device group processes at least a portion of the first image, and the at least one second graphics device is a part of a second graphics device group responsible for processing the second image, wherein each graphics device in the second graphics device group processes at least a portion of the second image, and wherein at least one of the first graphics device group or the second graphics device group includes more than one graphics device; delaying an operation of the second graphics device group to allow processing of the first image by the first graphics device group to advance relative to processing of the second image by the second graphics device group, in order to maintain sequentially correct output of the ordered sequence of images; and selectively providing output from the plurality of graphics devices to the display device, to display pixel data for the ordered sequence of images, wherein the plurality of graphics devices are arranged in a daisy chain configuration wherein pixel data from each of plurality of pixel devices is directed to the display device along the daisy chain configuration via the internal switching feature included in the plurality of graphics devices.
