Adders Half-adder ¾Adds two bits Produces a sumand carry ¾Problem: Cannot use it to build larger inputs FllFull-adder ¾Adds three 1-bit values Like half-adder, produces a sumand carry ¾Allows building N-bit adders Simple technique Connect Cout of one adder to Cin of the next These are called ripple-carry adders

Binary Adders: Half Adders and Full Adders
www.edwardbosworth.comBinary Adders: Half Adders and Full Adders In this set of slides, we present the two basic types of adders: 1. Half adders, and 2. Full adders. Each type of adder functions to add two binary bits. In order to understand the functioning of either of these circuits, we must speak of arithmetic in terms that I learned in the second grade.
