Study of Estimation Based Functional Iteration Approximation Dividers

Electronic implementation of mathematical operations is very important and critical part of digital system. The major aspects that must be considered are quotient convergence rate, hardware primitives, overheads, and mathematical formulation. Many algorithms were implemented to achieve dividers, which provide inflexible solutions without any percentage of error. In actuality there exist many error-resilient applications where such types of dividers fail to work satisfactorily in terms of power consumption and overall circuit performance. This paper highlights the different estimation or prediction-based dividers. In this paper, we highlighted the key feature points of conversion for approximation and functional iteration class dividers.
