PROBLEM TO BE SOLVED: To provide the signal processor of a small scale capable of being used in common for product-sum operations and division. SOLUTION: Plural signal processing elements 105 are cascade-connected and one signal processor provided with three signal paths is constituted. In the respective signal processing elements 105, for shift addition for the multiplication of a variable and a constant to be the base of the product-sum operation, first and second shifters 12 and 13 and an adder-subtractor 14 are used. For subtraction and a shift processing for calculating a partial quotient and a partial remainder in the case of the division, the adder-subtractor 14 and a third shifter 15 for shifting the result are used. The calculated partial quotient is transferred through a flag holding circuit 16 to the signal processing element 105 of a next stage. |
