PURPOSE:To quickly realize plural kinds of synchronization through the use of one electronic circuit even in the case that the defective electronic circuit exists in a system or the number of the electronic circuits is increased in the system constituted of plural electronic circuit blocks by providing the electronic circuit block with n-pieces of synchronization number buses and synchronization decision buses. CONSTITUTION:Four processing elements (PE0 to PE3) in a parallel computer are used as the electronic circuit block. Synchronization number broadcasting buses B3a, B3c and the synchronization decision buses B5a, B5c are connected to PE0, and two synchronization number buses B3 and synchronization decision buses B5 are connected to PE1 to PE3 as well. Then, when a synchronization number not used in the electronic circuit exists in the system, since the response duty of synchronization corresponding to the synchronization number informed from the synchronization number broadcasting bus B3 can be masked, the electronic circuit need not execute the processing of the synchronization for the synchronization number not to be used. |
