A graphics system is used with a display capable of displaying a frame of an image via a sequence of scan lines. The graphics system has a memory and an image generator. The image generator is connected to store the data associated with some of the scan lines of the frame in a region of the memory, and before all of the data is retrieved from the region, store other data associated with another scan line in the region. The graphics system also has a display interface that is connected to retrieve the data associated with some of the scan lines from the region and use the data to form some of the scan lines on the display. The display interface is also connected to use the other data to form the next scan line in the sequence after the other scan lines are formed.
