Abstract:
1. A method for toggling between video scanouts generated by a plurality of graphics processing units to produce a stereoscopic image, the method comprising: transmitting a set of programming instructions to a first graphics processing unit configured to generated video frames for display and to a second graphics processing unit configured to generated video frames for display; configuring, via a first instruction in the set of programming instructions, a first state machine within the first graphics processing unit to include a first indicator bit within a vertical blanking signal at the end of each video frame transmitted by the first graphics processing unit for display; and configuring, via a second instruction in the set of programming instructions, a second state machine within the second graphics processing unit to include a second indicator bit within a vertical blanking signal at the end of each video frame transmitted by the second graphics processing unit for display, wherein the first indicator bit is configured to cause a video bridge to toggle an output of the video bridge so that the video bridge transmits a video frame associated with the second graphics processing unit, wherein the second indicator bit is configured to cause the video bridge to toggle the output of the video bridge so that the video bridge transmits a video frame associated with the first graphics processing unit, and wherein the first graphics processing unit is configured to generate video data corresponding to a first perspective, and the second graphics processing unit is configured to generate video data corresponding to a second perspective, to produce the stereoscopic image.
