ABSTRACT:
A display controller includes a display memory having capacity for storing first and second memory lines of a display. A controller interrupts a CPU after each line is displayed so that the CPU writes a subsequent line to be displayed to the memory line whose data has just been displayed. The interrupt includes pointer information identifying which line has just been displayed and which line must be written to display memory by the CPU.
