Abstract

A binary adder employs separate summing and carry circuitry within each digit to optimize the speed of operation of the adder. Carry bits of less significant digits are calculated independently of corresponding sum bits, thus allowing propagation of such carry bits to more significant digits before completion of the summation of the less significant digits.
