PROBLEM TO BE SOLVED: To provide an arithmetic unit, with which a plurality of kinds of vectors can be operated while suppressing the expansion of circuit scale. SOLUTION: In an arithmetic unit 1 for performing arithmetic on the basis of input signals to become one set with (n) signal elements and coefficient groups to become one set with (n) coefficients corresponding to the respective signal elements, this unit is provided with input terminals 11a-11c for inputting the respective signal elements of the input signals, registers 90a-90c and 91a-91c for storing (s) kinds of coefficient groups, selectors 12a-12c for selecting out one kind of coefficient group out of (s) kinds of coefficient groups, (n) multipliers 13a-13n corresponding to the input terminals 11a-11c for mutually multiplying the mutually correspondent signal elements and coefficients, and an adder 14 for calculating out the total of the results multiplied by the respective multipliers 13a-13c. |
