Abstract
An apparatus for rapidly switching between output display frames using a shared frame identification memory is disclosed which has particular application to high resolution graphics for animation. Through a plurality of comparison circuitry, the apparatus enables a frame to be displayed during the clock cycles when the frame identification memory is read and during the clock cycles when the frame identification memory is provided with input, thereby, allowing a frame identification memory to be shared by two output display memories. As a result the rapid switching between output display frames sufficient for animation may be achieved with less hardware.
