METHOD AND APPARATUS FOR SENDING PARTIAL FRAME UPDATES RENDERED IN A GRAPHICS PROCESSOR TO A DISPLAY USING FRAMELOCK SIGNALS
First Claim
1. An apparatus comprising:
- a graphics processor operable to generate video frames, wherein said graphics processor is operable to begin generating a partial update region of a video frame upon receiving a framelock signal;
a screen refresh controller communicatively coupled with said graphics processor, wherein said screen refresh controller is operable to receive partial update regions of video frames from said graphics processor and send framelock signals to said graphics processor; and
a display device communicatively coupled with said screen refresh controller, wherein said display device is operable to receive and display video frames from said screen refresh controller.
