Area Efficient 4-Input Decimal Adder Using CSA and CLA

In Today we need exact results in our computation commercial application decimal arithmetic in their computation program it takes lot of time by software support we get results but system become slower so in this paper an area efficient 4-input decimal adder using CSA and CLA is proposed to give hardware support for decimal arithmetic synthesis shows that it reduces on chip area and consume less power with same propagation delay then previously proposed adder. It could perform complex addition as per our requirement
