Abstract
A high radix divider capable of reducing the size of the circuit of a quotient/remainder judgement unit in a radix 2 restoring division divider for finding a quotient k number of bits at a time, comparing multiples B, 2B, and 3B of a divisor B with a remainder R in parallel in two-input comparators and a three-input comparator and performing radix 4 division by finding a quotient 2 bits at a time. At this time, using a three-input comparator in the comparison of 3B=(B+2B)≦R to realize comparison without the addition (B+2B), also, finding a new remainder Re in a three-input adder/subtractor for the simultaneous complex addition/subtraction R−(x+y) by a single ripple carry.
