Abstract
A binary adder has a switching circuit connected to one of its inputs. When activated by a mode selection signal, the switching circuit forces two of the adder inputs to receive the same input signal. In this condition the adder acts effectively as a connector, coupling two of its inputs direct to the sum and carry outputs. The invention is useful in an array processor, for performing additions and shifting operations.
