PURPOSE:To provide a processor capable of shortening time required between the occurrence of an H/W event from a mouth or a keyboard and a drawing processing corresponding to the event and having improved real time characteristics permitting a user to easily use the device itself. CONSTITUTION:A system operates independently from the part controlled by a host processor (CPU) l and from a graphic device 13. The graphic device 13 includes a processor, a graphic card 8 including a VRAM, a graphic controller 9 and an FLCD panel 12. An OS is mounted in a computer main unit to run a process in time sharing. A drawing command generated by the process is transferred to the graphic card 8 via an AT bus interface 7. The graphic card 8 expands the drawing contents in a video RAM corresponding to the drawing command and manages the rewriting of a part specific to the FLCD panel 12 depending on the drawing contents. An event notification means monitors the execution state and compresses the event. |
