Short Note
A Design for an Efficient NOR-gate only, Binary-ripple Adder with Carry-completion-detection Logic
Computer Science Department, California State University, Northridge, CA 91330, USA
A novel way of designing a ripple-carry adder is presented. The new design uses only NOR gates. It is both economical, using only six NOR gates per stage, and efficient, since a carry-completion-detection circuit can easily be integrated into it at a cost of (approximately) one NOR gate per two adder stages.
