PURPOSE:To increase the scale of a distributed processing system by using a barrier processor which cascades the buses except a communication bus connecting plural slave processor except the slave processors to the communication bus. CONSTITUTION:A barrier processor 13 cascades the communication bus 4a except a communication bus 4 connecting plural slave processors 100a except slave processors 100 to the bus 4. The occupation of the bus 4a or 4 of the other side can be prevented by the communication carried out mutually between processors 100 connected to the bus 4 or 4a of one side. At the same time, the information which are transmitted and received between the processors 100 or the processor 100 and a main processor 200 connected to the different buses 4 cascaded to each other is relayed. In such a way, the independent communication is possible for each of communication buses divided by the processor 13. Then the processing ability of a distributed processing system is improved. |
