Explain block diagram for 4 bit parallel adder, Computer Engineering

Assignment Help:

What is parallel adder? Draw and explain block diagram for 4 bit parallel adder.

Ans:

By using full adder circuit, any two bits can be added along with third input like a carry. Full adder circuits are cascaded, if numbers of bits are more than one. Addend and Augend bits are applied concurrently at inputs to the full adders. Carry produced in the lower significant stage is transferred to the subsequent higher stage therefore this can be added there.
