Parallel Adder. Cout a nbits nbits s b nbits cin fig. There are different types of parallel adders as listed below.
A parallel adder is used to add two numbers in parallel form and to produce the sum bits as parallel outputs. In the circuit shown by figure 1 first fa 1 adds a 1 with b 1 to generate s 1 the first. Working of parallel adder.
What are the advantages of a parallel adder and a parallel subtractor.
In two numbers one is addend and the other is augend and both are added parallelly to get the sum. The output is in parallel form i e all the bits are added subtracted at the same time. Hence they are also faster than their serial counterparts. In the circuit shown by figure 1 first fa 1 adds a 1 with b 1 to generate s 1 the first.
