An adder is hardware blocks in almost digital and high performance system with advance in technology. Many researchers have tried and trying to design adder which offer either of high speed, low power consumption and low delay and small area. Thus making them suitable for various parameters in this paper, Carry Look-ahead Adder (CLA) and Ripple Carry Adder (RCA) both adders are 32 bit adders. These adders defined the low delay, small area and high speed. In this paper, all the simulation did on XILINX 14.2 design suit and ALTER QUARTU II S12.2 software.
