A video display processor generates display for displaying either a movable sprite or background via a display monitor or TV set operating a monitor. The video display processor includes a data port, at least one sprite register, a color palette, a color priority logic and a digital to analog converter disposed on a single integrated circuit. The color priority logic selects for supply to the color palette and the digital to analog converter a sprite color when the sprite location stored in a corresponding sprite register corresponds with the current raster scan position, otherwise the color priority logic selects color data received via the data port.
