Patent ID: 7689129

Claim:
Multiprocessor comprising: a plurality of processors having an optical communication function and capable of mutually cooperating; an optical transmission line interconnecting said plurality of processors, the optical transmission line comprising invariant optical paths; and a wavelength router provided on said optical transmission line and controlling optical communication between said plurality of processors, said wavelength router having a plurality of input ports and a plurality of output ports optically coupled to said optical transmission line, wherein said processors constitute a system-in-package configuration having a plurality of components mutually communicating electrically, said system-in-package has an internal input/output terminal to which both ends of said optical transmission line are connected, and a computation processing portion connected to said internal input/output terminal, and said computation processing portion has a control portion, a storage portion, and an application processor portion performing information processing, wherein: each of the plurality of processors has: at least one laser element emitting light of multiple wavelengths, a filter filtering said light of multiple wavelengths into light of a predetermined wavelength, and a light receiving element receiving said light of a predetermined wavelength; and one or more of said plurality of processors operate mutually asynchronously, and wherein said wavelength router is configured to receive light input to any one of said plurality of input ports from said optical transmission line and to output light to said optical transmission line via any uniquely determined output port of said plurality of output ports, responsive to the input port of the input light and the wavelength of the input light.
