Abstract
A method and apparatus for performing division which calculates a quotient from a dividend and a divisor by using recursive subtraction operations without using carry propagation for each subtraction operation. The apparatus contains a circuit (16) for generating a plurality of quotient digits from the divisor and the dividend. The apparatus also contains a circuit (18, 20) for generating the quotient from the quotient digits.
