Abstract
PURPOSE:To shorten the operation time, by providing registers capable of shifting and counting-up in the operating circuit, where an adding and subtracting circuit is used to perform the division and using the signal from the adding and subtracting circuit to perform the addition or the subtraction between the quotient and the third number simultaneously with the division. CONSTITUTION:In case of the operation of (a/b)+c, a numeric value (a) is set to the first shift register 5, and a numeric value (b) is set to the first register 3, and initial value 0 is set to the third shift register 2, and the register 5 is connected to the register in the first ring connection. Initial value 0 is set to the fourth shift register 10 connected to the register 5 and a gate circuit 8, and the second shift register 11 is connected to the register 10 in the second ring connection. Contents of the register 3 are subtracted from contents of the register 2 by an adding and subtracting circuit 1, and contents of registers 5 and 10 are shifted by the output of the circuit 8 and the operation is repeated when the output of the circuit 1 is negative; and 1 is added to lower bits of the register 10 when the output is positive, thus shortening the operation time.
