Abstract
A motion video image displaying apparatus and method of displaying is disclosed for displaying multiple fonts of video images in non-DMA mode for television-game machines. The inventive apparatus includes a status controller for generating a number of timing control signals. The apparatus comprises a parameter address generator for producing a parameter address based on the timing control signals and information issued by a CPU of the game machine; a tab address generator for producing a tab address based on the timing control signals, and for producing an overflow signal for the status controller; a color code address generator for producing a color code address based on the timing control signals, information read according to the tab address, and video information. Three tri-state buffers are also included for buffering the address outputs of the parameter address generator, the tab address generator, and the color code address generator, respectively, the buffers are controlled by the status controller to selectively output one of their buffered addresses. A video memory for storing and outputting video information and parameters based on the addresses generated by the parameter address generator, the tab address generator, and the color code address generator is also included.
