Question

A 128-bit parallel binary adder is to be constructed using Full Adderblocks only. How many Full Adder blocks are required?

Answer 1

A 128-bit parallel binary adder requires 128 Full Adder blocks.

Step-by-step explanation:

A 128-bit parallel binary adder can be constructed using Full Adder blocks. Each Full Adder block adds two binary bits and produces a sum bit and a carry bit. Therefore, for a 128-bit parallel adder, we need 128 Full Adder blocks.
