GRAPHIC DISPLAY DEVICE

PURPOSE:To draw pictures at a high speed by transferring again and directly the internal commands of all segments of each area designated in a picture memory as well as the control data, etc., from an external controller. CONSTITUTION:Such a mechanism is provided that transfers all data stored in a picture memory 5 at a high speed to an auxiliary memory device 9 like a disk of a host computer system 2. As a result, the quick rise is possible with an application system just by transferring the form of the data already stored in the memory 5 to another picture memory without reregistering the data in a desired reproduction state in a system start mode. A parallel data transfer interface is connected between the system 2 and a graphic CRT display device 1 or this device 1 is connected close to a bus of the system 2 in order to secure a high-speed rise of the application system.
