Abstract
A computing system performs non-restoring division. Quotient selection logic selects quotient digits that are used to produce a final quotient. The quotient digits are selected according to a predetermined relationship among certain bits of the divisor and the partial remainder. Only non-zero quotient digits are selected. A quotient accumulator combines each selected quotient digit with a current partial quotient concurrently while each quotient digit is selected. The quotient digits are selected and combined until the final quotient is produced.
