Abstract
PURPOSE: To extend the data to be compared and to reduce the comparison time, by taking the system that the coincidence of data is propagated from the upper to lower rank with the transfer gate.
CONSTITUTION: The data inputted to the input terminals 2a and 2b are inputted to the gates 21 and 22, where the discrimination of the input data A'i and Bi is made and that of Ai and B'i is made respectively. When Ai=Bi, the output of the gate 22 is 1 to conduct the transfer gate 23 and the coincidence signal 2c from the upper rank digit is delivered to the output terminal 2e to the lower rank digit. When the output of the gate 22 is 0 and the gate 23 is not conductive, the gate 27 corresponds to the pull up resistor and the coincidence output 2e is 1. In case of the discrimination of the magnitude of the input data, when the coincidence signal 2c from the upper rank digit is 0, the gate 15 is conductive with the gate 24 inverting the polarity of the coincidence signal.
