ABSTRACT:
A communication data switching apparatus for use between an input line, an output line, and a memory bus includes a receiver connected to the input line, a transmitter connected to the output line, a buffer memory for storing data received by the receiver and data to be transmitted by the transmitter, a memory transfer controller for controlling transfer of data between the buffer memory and the memory bus, and a main control unit for controlling the receiver, the transmitter, the buffer memory, and the memory transfer controller to store a signal which has been received from the input line by the receiver, in the buffer memory, to transfer the signal to the memory bus, to confirm whether data on the memory bus are addressed to a station to which the main control unit belongs, based on the content of the data, and to deliver the data through said transmitter to the output line if the data are addressed to the station. The communication data switching apparatus can quickly distribute a received signal to a plurality of stations. A communication data switching system may include a plurality of such communication data switching apparatus.
