Abstract
A display control system which includes a display memory having a serial access port for sending data to a display device and a random access port for data communication with a graphic drawing device. The system further includes a window buffer memory for storing image data such as sentences and graphic charts and a window controller for controlling the position of the window buffer memory content to be displayed on the display device. A selection circuit is included for selecting a display mode or a graphic drawing mode. During the display mode, the stored image data is transferred directly to the display device and overlaps the content of the display memory. During the graphic mode, the stored image data is transferred to the display memory under control of a graphic controller and is then displayed.
