Abstract
A 3x adder for adding 2a to a, where a is a binary number, the binary numbers 2a and a partitioned so that 2a=(x,. . . x,) and a=(y,. . . y,)where x,and y,have the same size for each i=0, 1, . . . , k, where the 3x adder provides the group generate terms for the sums x,+y,, i=0, 1, . . . , k, according to Boolean expressions, where for any sum x,+y,where x,and y,each have size n,+1, the number of Boolean variables in the product terms in the Boolean expression for the group generate terms of x,+y,do not exceed j+1, where j is the largest integer not exceeding n,/2.
