<p>PROBLEM TO BE SOLVED: To permit a host processor to precisely detect the termination of a processing in a graphic processor while the processing capacity of the host processor is prevented from being deteriorated as much as possible. SOLUTION: The graphic processor is provided with a geometry calculation part GC which converts graphic data becoming a display object into display graphic data displayed on a monitor by processing plural picture processing command information received from the host processor and accumulated in a command accumulation part 31 in accordance with the arranging order and with a rendering calculation part RC converting display graphic data obtained in the geometry calculation part GC into display picture element data on respective picture elements in accordance with the arranging order. The geometry calculation part GC and the rendering calculation part RC output interruption signals to the host processor based on an interruption signal generation command included in picture processing command information.</p> |
