Abstract
A data transmission system comprises an input data transmission line (1), an output data transmission line (4), a branching data transmission line (5) and a jointing data transmission line (7) formed respectively by asynchronous free-running shift registers using a plurality of data latches (101 to 106, 401 & 402, 501 & 502, 701 & 702) and, C elements (111 to 116, 411 & 412, 511 & 512, 711 & 712) respectively. A branching control circuit 3 supplies data to be branched to the branching data transmission line (5) in response to the decision by a branching decision circuit (2) as to the fact that the data to be branched is transmitted on the input data transmission line (1). A jointing control circuit (6) supplies data to be joined to the output data transmission line (4) in response to the decision by an empty buffer verifier (8) as to the nonexistence of data in the input data transmission line (1) and the output data transmission line (4) when the data to be jointed is transmitted on the jointing data transmission line (7). Thus, the data transmission system has branching and jointing functions and if it is used as a constituent of a network, data can be transmitted among asynchronous systems.
