Abstract:
1. An apparatus for processing image data to produce an image for covering an image area, comprising: a plurality of graphics processors, each graphics processor being operable to render the image data into frame image data and to store the frame image data in a respective local frame buffer; a control processor operable to provide instructions to the plurality of graphics processors; one or more merge units operable to synchronously receive the frame image data from the respective local frame buffers and to synchronously produce combined frame image data based thereon, wherein at least one of the one or more merge units is operable to produce a merge synchronization signal used by the graphics processors to release the frame image data from the respective local frame buffers to the one or more merge units; means for transmitting the entire combined frame image data to a single display; wherein the single display displays the entire combined frame image data on its image area; at least one synchronization unit operable to receive the merge synchronization signal from the at least one merge unit; and respective local synchronization units coupled to the graphics processors and operable to receive the merge synchronization signal and to cause the release of the frame image signal from the local frame buffer to the at least one merge unit.
