Abstract
A method and apparatus for storing and displaying multiple graphical images in a mixed video and graphics display is accomplished by determining an amount of memory sufficient to display a single graphics image in a subset of the display. Once the amount of memory required for a single image is determined, the pre-allocated portion of memory for graphics images is divided into an array. Graphics images are then rendered and stored within this array. One of the pre-rendered images is selected by a control block, wherein the selection is based on registers or parameters referenced by the control block. A display output engine fetches the selected one of the plurality of pre-rendered graphics images that is stored within the array and combines the selected graphics image with the video data stream to produce a display output stream. The display output stream is then fed to a display device that displays the graphics image.
