摘要：An arithmetic processing method is provided using a binary fixed-pointarithmetic processing circuit to carry out an operation of multiplicatively dividing a

dividend by a divisor. The method comprises shifting the divisor by a specific number ofbits when the absolute value of the divisor is within a specific range, and holding thedivisor without shifting the divisor when the absolute value of the divisor is out of thespecific range, acquiring an initial value of approximation calculation for the divisor that isshifted or held without being shifted, calculating a reciprocal of the divisor by performingasymptotic approximation of the acquired initial value more than once, and calculating aproduct of the calculated reciprocal and the dividend, and shifting the calculated productby the specific number of bits when the divisor is shifted.
