ABSTRACT:
Disclosed is a multiprocessor apparatus including a plurality of processors connected to a common bus, a co-processor provided in common to the processors, an arbitration circuit that arbitrates contention among the processors with respect to use of a resource in the co-processor through a tightly coupled bus by the processors and a multiplexer coupled to the arbitration circuit, coupled to the processors through a local buses, and coupled to the co-processor through the local buses to transfer the commands received from the respective processors to the co-processor in accordance with a permission signal output by the arbitration circuit.
