<p>PROBLEM TO BE SOLVED: To quickly inspect the state of each processor without making it necessary to arrange any extremely complicate electric wiring, or interrupting inter-processor data communication. SOLUTION: In this multi-processor system, 16 processors P0-P15 constituting a multiprocessor system 100 are circularly connected through a ring data bus 102, and grouped with each cluster constituted of four processors as a unit. Each cluster is constituted so that state information outputted from the first to third processors can be inputted to the fourth processor, and that the state information on which the states of all the processors in the same cluster are reflected can be outputted from the fourth processor. Also, the mutually adjacent clusters are constituted so that the state information outputted from the fourth processor in the cluster in the previous stage can be inputted to the first processor in the cluster in the next stage. Thus, it is possible to obtain the state information on which the states of all the processors are reflected by propagating the state information across the clusters.</p> |
