ABSTRACT:
A mechanism for dividing an integer dividend by an integer divisor to generate an integer quotient operates by aligning the divisor relative to the dividend such that a right-most bit of the divisor is aligned with a bit M of the dividend. The divisor is compared to an integer value whose right-most bits are equal to bits of the dividend which are aligned with bits of the divisor. As a result of this comparison, quotient bits which positionally correspond to the dividend bit M and to bits of the dividend which are located to the left of the dividend bit M are cleared to zero. Also as a result of the comparison, the dividend is divided by the divisor as aligned relative to the dividend to thereby generate values for any uncleared quotient bits.
