This paper presents a technique for fast addition of multi-digit BCD numbers. The addition of all columns can be performed simultaneously, and the carry values are utilized only in the final stage of the addition. Thus the traditional carry propagation process is drastically reduced, hence speeding up the addition process. The addition technique is used in the summation of partial products generated during a new multiplication approach proposed in the paper resulting in a faster multiplication.
