Multipliers Based on Approximate Compressors

Background: Approximate computing is an emerging trend in recent years that trades off the requirement of exact computation for the improvement of speed and power performance. Objective: Researchers are trying to improve the speed and power performance proposing different algorithms. Methods: This paper proposes approximate compressors used for the design of approximate multipliers. Results: By using the proposed method, approximate multipliers of different length have been synthesized and a comparative study with previously presented multipliers have been dealt here which shows that the proposed circuits have better speed and power. Conclusion: Finally, the proposed circuits have been used for image processing applications.
