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.

[What is claimed is:] [1.]a memory, wherein the memory includes a portion allocated to storing graphics information, wherein the portion allocated to storing graphics information is greater than an amount of memory sufficient to store graphics information to be displayed as a single image in a portion of a display, wherein excess memory of the portion allocated to storing graphics information is divided into an array, and wherein the array contains a plurality of pre-rendered graphics images for future display; anda display overlay engine operably coupled to the memory, wherein the display overlay engine fetches one of the plurality of pre-renderd graphics images from the array to produce a fetched pre-rendered graphics image and blends the fetched pre-rendered graphics image with at least one additional display data source to produce a display output signal to be provided to the display.
