MULTI-PROCESSOR SYSTEM USING AN OPTICAL COMMUNICATION WITH A DIFFERENT FREQUENCY BAND FOR EACH COMMUNICATION DESTINATION

摘要

A plurality of processors and at least one memory are optically connected each other through an optical fiber cable. Each of the plurality of processors and the at least one memory is assigned a different frequency band. Each of the plurality of processors has light emitting devices each corresponding to respective frequency bands of destinations. Each of the plurality of processors selects one of the light emitting devices. Each of the plurality of processors further has an optical filter passing through only optical signals of a frequency band that has been assigned to the processor. Each of the at least one memory also has a light emitting device and an optical filter the same as those in each processor. It is unnecessary to send information on destination addresses since the frequency band of optical signals identifies a destination.
