  • Coherence of displayed images for split-frame rendering in multi-processor graphics system
    Patent number: 7796135
    Abstract: Coherence of displayed images is provided for a graphics processing systems having multiple processors operating to render different portions of a current image in parallel. As each processor completes rendering of its portion of the current image, it generates a local ready event, then pauses its rendering operations. A synchronizing agent detects the local ready event and generates a global ready event after all of the graphics processors have generated local ready events. The global ready signal is transmitted to each graphics processor, which responds by resuming its rendering activity.
