PROBLEM TO BE SOLVED: To reduce the capacity of a storage unit in a dividing circuit.SOLUTION: A polynomial selection unit selects one of a plurality of input polynomial expressions each comprising a common factor and a partial polynomial expression, and supplies the partial polynomial expression in the selected input polynomial expression. A designation unit designates one of a plurality of first factors generated by factorization performed on the common factor in the selected input polynomial expression and one of a plurality of second factors each time an input polynomial expression is selected. A polynomial multiplication unit acquires a first remainder corresponding to the designated first factor and a second remainder corresponding to the designated second factor each time an input polynomial expression is selected, multiplies each of the first and second remainders and the supplied partial polynomial expression together, and supplies the result of multiplication. A polynomial addition unit adds up all of the supplied results of multiplication, and supplies the result of addition. A polynomial division unit performs a prescribed division on the result of addition, and outputs the result of division. |
