<p>PROBLEM TO BE SOLVED: To increase the speed for generating map data for a display device. SOLUTION: A system is provided with a detection mechanism 302, constituted so as to generate and store constitution data expressing a network and mutual connection, and when a network constitution is changed, it generates a constitutional change event and a layout mechanism 304 including a translator 103 for changing map data, based on the even and a graphic user interface 322 for receiving the map data from the translator 103 and driving a display device 108. The translator 103 stores an event in each periodical access, serves plural events during the period of a one-time access to a processor and correct the map data based on these events, so that the number of accesses from the translator 103 to the processor is minimized.</p> |
