Abstract : Approximate results are required in many embedded data processors as they reduce time delay and power. As error tolerance adder (ETA) has decreased power drastically trading with accuracy. This work focuses on reducing delay on existing adders when replaced with a fast adder. When compared to the past works on ETA, the proposed work has high power utilization and more accuracy of speed. The proposed design is compared and synthesized for the power and delay. When observed the existing ETA designs, the proposed work achieves significant improvement in power dissipation about 17.13%, 4.6%, 15.4%, 5.35% decrement for 4, 8, 16, 32 bits respectively, and significant improvement in delay about 28.90%, 23.59%, 20.08%, 24.44% decrement for 4, 8, 16, 32 bits respectively.
