PURPOSE:To shorten the time of transfer by making transfer from the leading of data number of times corresponding to the quotient obtained by dividing the number of bytes of data to be transferred by transfer unit having the maximum number of transferred bytes. CONSTITUTION:Data length of data to be transferred is counted by a byte counter 1. The counter selects a number 2 corresponding to maximum transfer unit from a dividor generator 3 that generates a number corresponding to fixed transfer unit by a selector 4 and sends it to a divider 2 and performs division. Transfer data stored in a buffer memory 5 are transferred from the leading according to the maximum transfer unit through a transfer controller 6 number of times corresponding to the quotient. Number of bytes of remaining transfer data is divided by the number of bytes corresponding to transfer unit having next size sent from the dividor generator 3 through the selector 4 and transferred from the leading of remaining transfer data number of times corresponding to the quotient. |
