Design flexibility and power consumption in addition to the cost, have always been the most important issues in design of integrated circuits. Power dissipation and energy consumption are especially important when there is a limited amount of power budget or limited source of energy. Recently advances in VLSI technology have made it possible to put a complete System-on-Chip (SoC) which facilitates the developments of PDAs, laptop, cellular phones etc. The evolutions of these applications profiles power dissipation as a critical parameter in digital VLSI design.
