PURPOSE:To display a graphic screen screen at a high speed by minimizing a time needed for transfer of graphic data to a graphic processor from a host computer. CONSTITUTION:When the graphic data are transferred to a memory buffer 5 from a host computer 1, a block final code showing the end of the transfer of data is written every time the transfer of the graphic data is through. At the same time, a graphic processor 4 reads periodically the buffer 5 and then judged the end of the transfer of the graphic data carried out by the computer 1. Thus a graphic screen is produced on a color keyboard 6 and displayed on a graphic display 7. As a result, the graphic screen is displayed at a high speed. |
