<p>The present invention has a plurality of barrier blades (BB8 and BB9), a barrier blade identification information storage unit (window storage unit 6), and a barrier blade identification information selection unit (input and output control unit 32). The plurality of barrier blades (BB8 and BB9) synchronize a plurality of processing units using synchronization addresses which have been set for the plurality of processing units. The barrier blade identification information storage unit (window storage unit 6) retains barrier blade identification information for identifying the barrier blades in accordance with synchronization address identification information for identifying the synchronization addresses for each of the plurality of processing units. When synchronization address identification information is input, the barrier blade identification information selection unit (input and output control unit 32) selects and outputs, among the barrier blade identification information retained by the barrier blade identification information storage unit, barrier blade identification information corresponding to the synchronization address identification information which has been input.</p> |
