PURPOSE:To realize a multistage and multipattern synchronization at high speed between many computers connected in multistages or a ring form by providing a synchronization holding register and a change over circuit for selecting the change over to transmit the synchronization pattern to a next stage or the like in the respective computers. CONSTITUTION:In a computer 11, a synchronization pattern from an arithmetic processing part 20 is written in a register 21, inputted a synchronizing signal bus circuit 26 through a synchronizing signal change-over circuit 23 and a synchronizing signal pattern from the computers 12, 13 is also inputted to a circuit 26. The synchronizing signal pattern in ANDed on the wiring, transmitted to a synchronization result input line 30 via a computer 1, the transmitted result and the synchronization pattern written in the register 21 are compared in a coincidence circuit 22 in the computer 11, and the coincidence result is transmitted to the arithmetic processing part 20. The serial operations are similarly produced to the computers 12, 13 to realize the synchronization of the computers 11-13. A synchronizing signal change over circuit 24 is changed over so as to transmit the signal of a synchronizing signal input line 27 to a synchronization result output line 28, thereby, the synchronization of the computers 111-113 is also realized. |
