Abstract
A microprocessor with Booth multiplication, in which several acquisition registers are used. In a first word length, a first acquisition register stores an unsigned ending acquisition of a first multiplier number carried in multiplier number supply data, and a third acquisition register stores a starting acquisition of a second multiplier number carried in the multiplier number supply data. In a second word length that is longer than the first word length, a fourth acquisition register stores a middle acquisition of a third multiplier number carried in the multiplier number supply data. A partial product selection circuit is required for selection of a partial product, to get the partial product from Booth multiplication based on the third acquisition register (corresponding to the first word length) or based on the fourth acquisition register (corresponding to the second word length).
