Abstract:
1. A method for processing a 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 of the plurality of graphics devices 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 sequence of images, wherein the at least one first graphics device processes certain ones of the sequence of images, including a first image, and the at least one second graphics device processes certain other ones of the sequence of images, including a second image; delaying processing of the second image by the at least one second graphics device, by a specified duration, relative to processing of the first image by the at least one first graphics device, to stagger pixel data output for the first image and pixel data output for the second image, wherein the specified duration is determined by dividing an estimate of processing time for an image by a number of graphics devices used to process the sequence of images; and selectively providing output from the at least one first graphics device and the at least one second graphics device to the display device, to display pixel data for the 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.
