5~ Concluding Remarks
As for other digital modules, the design of a digit recurrence division unit is a
trade-off among several characteristics, such as execution time, area, and energy.
We have shown that the main parameters to consider in this trade-off are the
radix of the quotient digit obtained each iteration and the quotient-digit set. We
have given some example implementations that show the speedup achieved for
higher radices, as well as the increase in area.
A higher radix reduces the number of iterations, but complicates the selection
function and the multiplication of the divisor by a quotient digit. The use ...
