Multi precision arithmetic adders

Arithmetic adder is the most important basic element for many digital applications. In this paper different types of adders are taken for experimental study such as Ripple Carry Adder, Carry Save adder, Carry Look ahead adder, Carry Increment adder, Carry Select adder, and Carry Skip adder. Here in this paper introducing a novel technique for designing a new Carry Select adder for multi precision arithmetic circuits. By using this technique improvements has been achieved like low latency and less power consumption and along with less gate count. Experimentally synthesized and simulated by using Xilinx ISE14.7, also tested in SPARTAN3E, XC3S1600E with speed of −5.
