What is High-Speed Function Approximation Techniques about?
This document discusses a method for high-speed approximation of functions like reciprocal, square root, and trigonometric functions in single-precision floating-point format using table lookup and a minimax quadratic interpolation. The method aims to achieve fast execution times comparable to linear approximation methods while requiring less area than other quadratic interpolation algorithms. It uses an enhanced minimax approximation approach that takes rounding of polynomial coefficients into account to f
