Abstract

PURPOSE:To secure the propriety of data transfer and to shorten the time of the data transfer, by collating the number of data transfer incication signals that a transmission side transmits with that of data reception indication signals that a reception side sends. CONSTITUTION:An input-output controller 2, when sending data, sends a sink-in signal onto a sink-in signal line 4 simultaneously, The data are sent out one after another without waiting for a sink-out signal from a reception side, and the sinkin signal is sent for each time. The number of the sink-in signals is counted by a collation part 10. A channel 1 receives the data corresponding to the sink-in signals and returns sink-out signals each indicating data reception. The collation part 10 observes the numbers of the sink-in signals and sink-out signals to secure the propriety of the data transfer.
