It includes a selection unit which provides an extension bit for performing an unsigned magnitude multiplication in a signed magnitude multiplication which is expressed by a two's complement format, and a partial product generator for performing a sign digit operation increased by the extension bit. It preferably includes a carry look-ahead adder for generating and propagating a look-ahead carry.
