BINARY ADDER Russian patent published in 2021 - IPC G06F7/501 

FIELD: computing technology.

SUBSTANCE: disclosed is a binary adder containing seven EXCLUSIVE-OR elements and three AND elements, wherein the first, second inputs of the r^th EXCLUSIVE-OR element and the output of the first EXCLUSIVE-OR element are connected with the r^th, (3+r)^th input and the first output of the binary adder, respectively, wherein additionally introduced thereto are four majority elements, the r^th input of the i^th and the first, second inputs of the j^th EXCLUSIVE-OR elements are connected with the r^th input of the i^th majority element and the first, second inputs of the (j-4)^th AND element, respectively, the first, second inputs of the k^th , the first, second inputs of the seventh and the first, second, third inputs of the fourth EXCLUSIVE-OR element are connected with the outputs of the (k-4)^th majority element, the (k-3)^th EXCLUSIVE-OR element, the first AND element, the sixth EXCLUSIVE-OR element and the third, second AND elements, the third majority element, respectively, and the third input of the r^th EXCLUSIVE-OR element and the output of the fourth majority element are connected with the (6+r)^th input and the fifth output of the binary adder, respectively, the second, third and fourth outputs whereof are formed by the outputs of the fifth, seventh and fourth EXCLUSIVE-OR elements, respectively.

EFFECT: ensured addition of three three-digit binary numbers set by binary signals.
