An Efficient VLSI Design of 4-bit ALU

Energy dissipation has emerged as one of the highest important factors in the formation of VLSI. Now a days each and every electronic gadget has been designed in a smart way with lot of applications, hence these may dissipate higher power. Reversible logic has got higher interest in current trends because, its characteristics are less heat dissipation capability. This logic plays crucial role for the construction of low power structures.
