Abstract
PURPOSE:To improve communication efficiency by executing a data re- transmission request based on the logical sum of data reception success in a transmission sequence yet achieved. CONSTITUTION:The following three are provided: a first register group 10 to store the results of the logical sums of the success/unsuccess of the reception of a data transmission command string on necessities as to the initial transmission sequence and the re-transmission sequence, a second register group 11 to store the success/unsuccess of the reception of a data transmission command string of the initial transmission sequence or the re-transmission sequence that is currenty executed, and a logical sum circuit 12 that operate the logical sum between a first register group 10 and a second register group 11. The content in the first register group 10 is updated by using the result of said logical sum operation, and re-transmission request is continuedly transmitted to a transmission source processor 1 until the result of the logical sum operation shows the successes of reception of all the data transmission commands. As a result, the number of useless retransmission requests or the times of initilization of data re-transmission sequence can be reduced.
