Abstract
A division algorithm in which the quotient-digit selection is performe d by rounding the shifted residual in carry-save form is presented. To allow the use of this simple function, the divisor (and dividend) is prescaled to a range close to one. The implementation presented result s in a fast iteration because of the use of carry-save forms and suita ble recodings. The execution time is calculated and several convenient values of the radix are selected. Comparison with other dividers for radices 2(9) to 2(18) is performed using the same assumptions.
