PURPOSE:To accelerate arithmetic computation by shortening the arithmetic time by continuously executing the multiplication of polynomials by composing plural arithmetic elements, which output the products and sums of plural inputs, of a two-dimensional array. CONSTITUTION:An arithmetic element 1 is composed of a selector, multiplier, adder and register or the like and outputs the product and sum of a first input C and second and third inputs B and J. This arithmetic element 1 is arranged longitudinally for (a) columns and laterally for (b) steps, and the respective arithmetic elements 1 are connected so that the (i-1)th degree coefficient of a given (a-1)th degree polynomial lambda(x) and the (j-1)th degree coefficient of a given (b-1)th degree polynomial S(x) can be second and third inputs B and J at the arithmetic element 1 arranged at the i-th column and j-th step when the output of the arithmetic element 1 arranged at the (i+1)th column and the (j-1)th steps is the first input C. Then, a general polynomial M(x)=lambda(x).S(x) not having x<->b as the modulus is calculated. |
