The tag channel consists of at least a write service in line and a read service in line, wherein the write service in line transfers a signal which indicates, when the write operation is being conducted, whether or not the information on the data channel and the address channel are available, while the read service in line transfers a signal which indicates, when the read operation is being conducted, whether or not the information on the address channel are available, whereby a write operation and a read operation are alternately specified in the system without errors. Further, a single means for providing a bus busy signal is mounted in the system. After one of the data processing unit or input/output control units has requested to occupy the common bus for carrying out the write operation or for carrying out the read operation and after such occupation of the common bus, the bus busy signal is provided from the single means. - 1 -
