Each data unit is (1/2)k word. The vector load instruction generating unit generates an instruction to load a second group of data units, which is used as an element [i+2k] into a second vector register. A vector shift double instruction generating unit generates an instruction to cause a part of a data string, which is obtained by shifting data of the first vector Register and the second register by (1/2)k word as a series of data string, to be stored in a third vector register in a state of being packed in units of 1-word.
