PURPOSE:To decrease the number of signal transmission lines and to improve efficiency for synchronous processing and data conversion to attain the simultaneous processing of transmission and reception, by processing simultaneously both fixing of synchronism and data exchange between processors and allotting a specific wavelength to each processor to perform multiplexing of optical wavelength. CONSTITUTION:Computers 26-28 deliver a command to a transmitter TX with the function within a command word defined as a synchronous pattern in order to obtain synchronism among processors 11-13. The transmitter TX performs a serial transmission with an optical signal. The reception side checks the function and applies an interruption to computers 26-28 if the synchronism is obtained. Thus the synchronous processing is carried out. The transmitter TX transmits the data after designating the destination of the data and the number of data. The reception side confirms the data transfer to own station and stores successively the transmitted data to designated memories. When this storage is over, the end of reception is informed to the computers 26-28. Processors 11-13 have two receivers RX1 and RX2, and therefore the receptions are through simultaneously with two stations as long as the number of transferred data is equal. This fact means that the transfers are through simultaneously among three channels. |
