PURPOSE:To perform the multiplex control including the single operation control, the duplex operation control and the dual operation control in a simple computer system and in accordance with each task. CONSTITUTION:Each of CPUs connected to a bus which is connected to a communication processor distributs the messages via a message selection control part 211 to send a message to each task processing part. A processing system control part 212 controls the processing system of each task processing part and also controls the system constitution. A task processing control part 214 controls the processing forms of the single, duplex and dual. processings. Then an other-system monitor control part 213 performs the control of operations of other systems and the transfer of the fault information. In such a constitution, the duplex and dual task processing parts, in particular, perform the controls in response to the state changes of the task processings to be paired with other systems. |
