ABSTRACT:
A data transmission apparatus includes one input-side transmission path and a plurality of output-side transmission paths. The input-side transmission path includes a plurality of handshaking-type data transmission paths provided in series. Each of the output-side transmission paths includes a plurality of handshaking-type data transmission paths provided in series. Data to be transmitted includes an identifier for designation any or all of the plurality of output-side transmission paths. A comparison and determination logic portion determines whether the identifier included in the data designates any of the plurality of output-side transmission paths or all of them. A control portion sends the data supplied from the input-side transmission path to any or all of the plurality of output-side transmission paths, in response to a signal outputted from the comparison and determination logic portion.
