  • Patent number: 5969728
    Abstract: A graphics system including a frame buffer having two or more buffers, a graphics processor and system memory. The graphics processor includes rendering logic, display logic and a buffer switch memory that stores an address. The display logic reads the address from the buffer switch memory and retrieves rendered data for display from one of the buffers. The rendering logic retrieves a next display list from the system memory after a continue indication is provided, renders the retrieved display list into another buffer, writes an address corresponding to the other buffer into the buffer switch memory and clears the continue indication. The continue indication may be a separate bit or a continue flag provided within each display list. The rendering logic sequences through the plurality of buffers in this manner to render a plurality of display lists. If only two buffers are provided, then the buffer switch memory includes an arm bit and the rendering logic sets the arm bit after rendering each display list.
