Abstract
PURPOSE: To improve a screen movement speed by providing a refresh memory larger than the display screen in a CRT and by displaying an arbitrary part of the refresh memory on the display screen.
CONSTITUTION: All data of a virtual large screen to be set is outputted from processor unit 17 to refresh memory 12. Next, hardware of the CRT scans a part of refresh memory 13 indicated by window position counter 14 and converts it to a video signal, thus displaying a part of the virtual large screen on display screen 11. In case that the operator wants to move the screen, joy stick 15 is turned to the movement direction. By this operation, interruption is caused to firmware 16, and firmware increases or reduces XY as requested. Thus, display screen 11 moves in the virtual large screen.
