Zusammenfassung:PROBLEM TO BE SOLVED: To synchronously execute the same processing between plural processing units without increasing the processing load of an operating system. SOLUTION: At the time of outputting start requests for reading out various state information from respective processors 3, 4, processing units 1, 2 respectively collect and enter various state information from the other processing units 2, 1 at the same time through synchronous transmitting/receiving data buses 13, 14 in addition to the state information of their own processing units. State information reedited to a prescribed format common to all the processing units are returned to the processors 3, 4 at the same timing together with the various state information of their own processing units.
