Abstract
An apparatus for controlling power delivery from a power source to selected portions of a multiplying device for determining the product of a first number having a first plurality of digits and a second number having a second plurality of digits. The multiplying device includes a plurality of components which include a plurality of multiplier units for determining a plurality of partial products and a register unit for storing information, the register unit including plurality of register cells for accumulatingly storing the partial products according to a predetermined arrangement; the apparatus includes: a power bus for providing controllable delivery paths for delivering the power from the power source to the multiplying device; and a control unit for controlling the delivery paths to selectively effect operational connection between specified components and the power source. The control unit includes a logic unit for comparing the first number with the second number and determining the greater number of digits between the first number and the second number. The control unit employs the greater number of digits to selectively provide the power to specified components of the plur…
