Question

If you want to build full adders to add two 4-bit numbers with Cin and Cout, how can you build this module? Draw the block diagram of this full adder.

Answer 1

To build a full adder module for adding two 4-bit numbers with Carry-In and Carry-Out, you would need four full adders.

Step-by-step explanation:

A full adder is a logic circuit used in digital computers to perform arithmetic operations. To build a module that can add two 4-bit numbers with carry-in (Cin) and carry-out (Cout), you would need four full adders. Each full adder takes in two bits from the two input numbers and the carry-in bit, and produces a sum bit and a carry-out bit.

The block diagram of a full adder consists of three inputs: A, B, and Cin, and two outputs: S (sum) and Cout (carry-out). Each full adder takes in these inputs and produces the corresponding outputs. Here is the block diagram:
