Graphic display unit and graphic display method using the same
 The data transferred from a computer to the accelerator are stored in the transfer data storage region together with the transfer flag that indicates the destination of transfer. The transfer data determination unit determines the destination of data transfer from the transfer flag, and the graphic data that do not need to be extended are directly written into the graphic data storage means of the accelerator, and the graphic data that do need to be extended and the control data are written into the shared memory. The graphic data are extended by the graphic data extension processing unit and are written into the graphic data storage unit. The interrupt control unit and the interrupt processing unit work to change over the writing of graphic data into the graphic data storage unit and bring the output from the transfer data determination unit into synchronism with the output from the graphic data extension processing unit. The graphic data processing unit processes the graphic data written into the graphic data storage means and displays the data on the display unit.
