Although Adders are no doubt very important feature of Central Processing Unit (CPU) and All the Arithmetic calculations are performed in CPU by using Adder. Apart from all these features, some of the additional benefits of Adders are: Ripple Carry Adder works very slow in case of multiple bits addition. A half adder combines two bits to generate a sum and a carry The reason for Ripple Carry Adder to be slow is because it performs the computation even after the bit generated by addition of two binary digits generated by Look Ahead Carry Adder.
