Very high radix division with selection by rounding and prescaling
A division algorithm in which the quotient-digit selection is performed 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 results in a fast iteration because of the use of carry-save forms and suitable recodings. The execution time is calculated, and several convenient values of the radix are selected. Comparison with other high-radix dividers is performed using the same assumptions.<>
