Binary addition is the most fundamental arithmetic operation. It has been ranked the most extensively used operation among a set of real-time digital signal processing benchmarks from application-specific DSP processors to general-purpose processors. In Carry SeLect Adder (CSLA) is one of the faster adder used in many data-processing processors to perform fast arithmetic functions. The speed of operation of such an adder is limited by carry propagation from input to output. This paper discusses about the implementation of linear Carry SeLect Adder (CSLA) with Kogge-Stone Adder. The Kogge-Stone parallel approach will give option to generate fast carry for intermediate stages.
