This paper presents a low power and high-speed multi-operand adder which shows a higher degree of modularity than other existing adders. In Digital Signal Processing (DSP) applications, Addition is one of the fundamental operations. In advance technology, researches are still going on to design an adder that carries out addition in a twinkle of time. Carry Save Adder (CSA) is one of such high speed and low power adder. This paper focuses on the designing and simulation of carrying Save Adder (CSA) using Carry Look ahead adder instead of using usual ripple carry adder so that speed increases by 10%.
