ABSTRACT:
Transfer of data can be controlled by connecting operation modules, which share a single-circuit data bus line, together by a single-circuit handshake line, allocating the timing of use of the data bus line by time-division techniques in synchronization with a handshake clock when sending out and accepting data among the operation modules, and forming a gate circuit via the handshake line between two of the operation modules, whereby to detect coincidence of a data send ready state and a data accept ready state in the two of the operation modules. The above controlling method permits use of fewer control line, simple pipeline processing, shorter standing time, etc.
