Binary AdderThe registers play an important role in performing the microoperations. The registers hold the digital component and the data which performs the arithmetic operation. The Binary Adder is a logical circuit which is used to perform the addition operation of two binary number of any length. The Binary Adder is formed with the help of the FullAdder circuit. The FullAdders are connected in series, and the output carry of the first Adder will be treated as the input carry of the next FullAdder. NBit Parallel AdderThe Full Adder is used to sum two singlebit binary numbers with carry input. In digital calculation, we need to add two nbit binary numbers rather than only singlebit binary numbers. For this purpose, we need to use nbit parallel Adder. In order to get Nbit parallel adder, we cascade the n number of Full Adders. The carry output of the first Adder is treated as the carry input of the second Adder. 4bit Binary Adder
