Two registers R2 and R3 are used as input operands. The upper and lower sides of the register R2 are compared, and a value selected in accordance with the comparison result is stored on the upper side of another register R4. The upper and lower sides of the register R3 are compared, and a value selected in accordance with the comparison result is stored on the lower side of the register R4. Data on the upper and lower sides of the register R4 are simultaneously read out and stored at adjacent addresses in a memory (16) via a 2-word width bus (17) or bus (18).
