主权项

1. A microprocessor chip for performing optical communication with at least one external device, the microprocessor chip comprising:
a first processor including a first optical transceiver; a second processor including a second optical transceiver; at least one first optical input/output unit that is formed in the microprocessor chip and is configured to receive optical signals from the at least one external device and transmit optical signals to the at least one external device; an optical system bus that is connected between the first and second transceivers and the at least one first optical input/output unit; and a first optical bus arbiter that is configured to control transmission of an optical signal on the optical system bus, wherein the at least one first optical input/output unit includes,
at least one first optical connector that is exposed to an area outside of the microprocessor chip and is configured to connect with a second optical input/output unit of the at least one external device; andat least one first optical switch that is connected between the at least one first optical connector and the optical system bus, wherein the first optical bus arbiter is configured to control the first optical transceiver, the second optical transceiver, and the at least one first optical switch to determine connection relation between the first and second transceivers and the at least one first optical connector.
