<p>PURPOSE:To provide a multiprocessor system circuit in which the generation of a phase difference at a clock pulse applied to each processor can be always prevented, and each processor can be synchronously operated, regardless of the number of the processors, or the increasing frequency of the clock pulse. CONSTITUTION:Plural processors 11, 12, and 13 which necessitate the supply of the clock pulse for the operation are provided on the same board in a multiprocessor system circuit. This system is equipped with plural clock pulse generators 8, 9, and 10 provided at each processor 11, 12, and 13, and a synchronizing means which obtains a synchronization among the plural clock pulse generators 8, 9, and 10. The synchronizing means is constituted of a synchronizing signal generating circuit 2 which generates a synchronizing signal, light emitting element 3 which converts the synchronizing signal generated by the synchronizing signal generating circuit 2 into an optical signal, and emits it, and light receiving elements 4, 5, and 6 provided at each clock pulse generator 8, 9, and 10, which receive the optical signal from the light emitting element 3, convert it into an electric signal, and apply it to the clock pulse generators 8, 9, and 10.</p> |
