Summary:A microprocessor comprises a calculation unit that (i) includes partial calculation units each operable to perform partial data calculation, and (ii) is operable to perform data calculation on N or less bits, where N is a total number of bits on which the partial calculation units are to perform data calculation. The microprocessor, when having the calculation unit perform data calculation according to an instruction fetched from a memory, controls the partial calculation units depending on a bit width mode selected in terms of a number of bits on which data calculation is to be performed, so as to either (i) have all the partial calculation units operate, or (ii) suspend operation of a predetermined number of the partial calculation units, and have the rest of the partial calculation units operate.
