<p>PURPOSE:To output a data in the order of arrival by switching the data to an output port while taking the order of input presence signals set when the data reaches an input port into account. CONSTITUTION:Data from plural input ports 1 are stored in respective memories 3 and when the data reach the memory 3, the memory 3 informs an input presence signal IP to an output port output control section 8. The output port output control section 8 arranges the input presence signal noticed when the data from each input port is stored in the relevant memory 3 sequentially, controls a multiplexer 25 so that the data is outputted to the output port 2 in the order of the signal IP when the data is outputted to the output port 2 succeedingly. Thus, the data from the plural input port 1 is outputted to the output port 2 in the order of first-come and the undesired residence of the data is prevented.</p> |
