Abstract
A device for multiplying two bit sequences has a controller that selects and activates exactly one multiplier unit from a plurality of parallel multiplier units, according to a random signal. A partial multiplier unit shared by all the multiplier units receives and multiplies operands formed by the respectively activated multiplier unit. Each multiplier unit implements a different multiplication method with a respective selector unit that selects segments of the bit sequences to be multiplied, in accordance with a selection plan adapted to the respective multiplication method, to form operands from one or more segments and outputs the operands. The respective accumulation unit receives step by step partial products from the partial multiplier unit, accumulates the partial products in accordance with an accumulation plan adapted to the implemented multiplication method and matching the selection plan, and outputs the calculated product of after accumulation has been completed.
