GENERAL-PURPOSE DISPLAY CONTROL APPARATUS FOR ELECTRONIC GAME APPARATUS

摘要

A general purpose controller suitable for use with an electronic amusement game having a raster scan display receives game data from the game during vertical blank periods, the game data specifying object images and their screen positions desired for the next display in the sequence of raster scan displays. The controller then reads color/intensity information for each display pixel out of permanent memory at the time the pixel is displayed on the raster scan display surface. An embodiment is described capable of controlling up to 32 object images in the play of a game.
