ABSTRACT:
A plurality of picture RAMs are synchronously accessed by a CRT controller, and the priority levels of the outputs from the picture RAMs are specified by priority specifying means. A priority circuit has as inputs the outputs of the picture RAMs and selects the inputs in accordance with the specified priority levels for output to a color display. The color display displays, on its CRT screen, graphic forms in colors determined by a combination of the picture RAMs. A feedback circuit feeds the output of the priority circuit back to the picture RAMs, and data update control means specifies which one of the picture RAMs is to be rewritten with the output of the feedback circuit. By hardware processing the stored content of a desired one of the picture RAMs is rewritten with the output of the priority circuit.
