ABSTRACT:
Half-adder logic modules employing separate summing and carry circuitry are used in the construction of a modular binary half-adder. Carry bits of less significant digits are calculated independent of and prior to the calculation of corresponding sum bits, thus allowing rapid propagation of such carry bits to more significant digits and subsequent parallel summation of the sum bits using the carry bits previously calculated.
