Title: Binary carry cutting adder
Inventor: SUGIMURA YUKICHI
IPC: G06F7/50
Filed: 1997-01-16
Abstract: PROBLEM TO BE SOLVED: To attain the addition of thirty-two binary digits by seven gates and six fan-in. SOLUTION: Respective binary digits AB=10, 01 are inputted to an OR gate G1 and respective digits 11, 00 are inputted to an OR gate GO. An output from the gate G1 is inputted to an OR gate 1 when an AND gate St is ON or inputted to an OR gate 0 when an AND gate De is ON. AN n-digit AND gate '11' signal is sent to an m-digit AND gate De through an AND gate Dmn → signal OR gates → the and gate De. The NOT result of all '00' signals of (m-1) to (n+1) digits is inputted to the AND gate Dmn through several OR gates and cut out. When an n-digit '11' signal is cut out, the gate St is turned on. The processing is applied to all n=(m-1) to 1 digits. Thus the sum of thirty-two digits is obtained by seven gates. In the case of an adder of thirty- two digits, m=32 to 2. A '00' signal can be cut out by an '11' signal.
