The most fundamental operation of any processor is the addition. For any circuit there are two important parameters that comes into count is high speed and low power consumption. Hence the speed of various modules should be maximized to dominate overall performance. Depending upon these parameters various adders can be invented like Carry Look Ahead Adder(CLA),Carry Skip Adder(CSA) and Ripple C...

The power-delay product is a direct measurement of the energy expanded per operational cycle of an arithmetic circuit. Lowering the supply voltage of the full adder cell to achieve low power-delay product is a sensible approach to improve the power efficiency at sustainable speed of arithmetic circuits composed of such instances at high level design. In this paper, a novel design of a low power...
