Abstract

The invention relates to a division operation method, device and equipment. The division operation method comprises the following steps of: generating first quotient data through obtaining a sign bitof a dividend, carrying out shift prejudging on an intercepted to-be-prejudged data and a divisor, and when second register data is smaller than or equal to the divisor, shifting first register data leftwards for a preset shift number until the second register data is greater than the divisor so as to generate second quotient data; when the second register data is greater than the divisor, carrying out alternating addition and subtraction operations on the first register data until 1 is added to a quotient and the second register data is smaller than or equal to the divisor so as to generate third quotient data; and carrying out array output on the first quotient data, the second quotient data and the third quotient data according to generation time from high order to low order so as to obtain a quotient operation result. According to the method, the operation period is shortened, the division operation speed is greatly improved and then the division operation efficiency is improved.

Description

technical field [0001] The invention relates to the field of digital signal processing, in particular to a division operation method, device and equipment. Background technique [0002] In digital signal processing, division operations are often involved, such as the calculation of the normalized minimum mean square error. In the algorithm to realize the divider circuit, the commonly used methods include the method of restoring the remainder, the method of alternating addition and subtraction, and the division of fixed-point numbers. [0003] Among them, the divider of the recovery remainder method converts the division operation into a shift operation and a subtraction operation, and directly subtracts the divisor from the dividend / remainder. If the remainder is sufficient, the upper quotient is 1; if the remainder is insufficient, the upper quotient is 0. , at this time, the divisor must be added back and restored to the original remainder in order to continue the calcula...
