Design ripple carry and carry lookahead (CLA) adders.Ripple Carry AdderDesign a 16 bits adder electronic circuit using cascading one-bit full adders connected in cascade(seen in the class). This type of adder is called Ripple Carry Adder with the carry output fromeach full adder connected to the carry input of the next full adder in the chain.ï‚·Use optimization techniques to use a minimal number of gates.Assuming the delays given by the gates is as follow:Calculate Delays for the outputs of a 16-bit ripple carry adder normalized to an inverter delay.One-bit full adderCarry lookahead adder (CLA)Write a Boolean function of Ci+1 and Si based on above assumption.Design the one-bitlookaheadadder and the full implementation of the 16 bitslookahead adder.Calculate the time for the 16 bits addition operation using lookahead carry.
