Abstract
An information processor used as a processor in a personal computer for example includes an inner-product operational unit which effects an SIMD type inner-product operation. The result of the inner-product operation effected in the inner-product operational unit is stored into a P register in the form of a word. A shift and shifting unit reads the result of the inner-product operation stored in the P register , 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 as a sub-word.
