  • Patent number: 6331854
    Abstract: A method and apparatus for accelerating animation in a video graphics system is accomplished by storing drawing operations for a first scene in a bus master buffer. The first scene is to be drawn to a first frame. A frame flip operation is then stored in the bus master buffer at a location subsequent to the drawing operations for the first scene such that when accessed by a graphics processor, the frame flip will be performed after the drawing operations for the first scene have completed. Drawing calculations for a second scene to be drawn to a second frame are performed, and the resulting drawing operations are stored in the bus master buffer at a location subsequent to the page flip operation. The graphics processor is signaled, and the graphics processor fetches and executes the commands in the bus master buffer sequentially such that the drawing operations to the first frame are performed first, followed by the frame flip operation and finally the drawing operations to the second frame.
