A binary adder stage in which the two binary inputs are logically combined to produce the Exclusive-OR, the Exclusive-NOR, the NAND and the NOR functions of the two inputs. The carry-input signal is then used to control the generation of the sum output and the carry-output. When the carry-input signal has one binary value, the Exclusive-OR function and the AND function of the binary inputs are produced at the SUM and COUT outputs. When the carry-input signal has the other binary value the Exclusive-NOR function and the OR function of the two binary inputs are produced at the SUM and COUT outputs.
