摘要：
An integer division system for a dividend and a divisor includes a pre-calculation module to select a reciprocal approximation and a rounding error compensation value of the divisor, and an instruction generation module to generate at least an instruction to calculate a quotient of the dividend using the reciprocal and the rounding error compensation value. The reciprocal approximation is of the same predetermined number of binary bits as the divisor and the pre-calculation module determines which one of rounding-up and rounding-down is used when selecting the reciprocal approximation and the rounding error compensation value.
