Abstract
A method for performing decimal division including receiving a scaled divisor and a scaled dividend into input registers. A subset of multiples of the scaled divisor is stored in a plurality of multiples registers. Quotient digits are calculated in response to the scaled divisor and the scaled dividend. Each quotient digit is calculated in three clock cycles by a pipeline mechanism. The calculating includes selecting a new quotient digit, and calculating a new remainder. Input to the calculating a new remainder includes data from one or more of the multiples registers.
