CONSTITUTION:Application tasks 1 form the commands corresponding to the information to be displayed on a display device. A graphic task 3 successively accepts the commands from these plural application tasks 1 and outputs the commands to a plotting processor 5 so as to have these commands executed by this plotting processor 5. The plotting processor 5 receives the commands and forms the information that the display device can display. A top priority graphic task 4, in place of the graphic task 3, accepts the command of the high priority, further applies interruption to the plotting processor 5 and has the command of the high priority executed by the plotting processor 5 when the command of the higher priority than the priority of the commands is formed in the case the graphic task 3 has the commands executed by the plotting processor 5. |
