摘要: An information processor 1 used as a processor in a personal computer for example includes an inner-product operational unit 3 which effects an SIMD type inner-product operation. The result of the inner-product operation effected in the inner-product operational unit 3 is stored into a P register 15 in the form of a word. A shift and shifting unit 16 reads the result of the inner-product operation stored in the P register 15, shifts the result by an arbitrary number of bits and then clips it with the arbitrary number of bits, and stores the result into a Y register 17 as a sub-word.
