Abstract
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.
Keywords: Approximate compressors, approximate multiplier, image processing, approximate computing, proposed circuits, exact computation.
