The CORDIC algorithm calculates a set of elementary functions which include trigonometric, hyperbolic and their inverse functions as well as multiplications and divisions. We report on the parameter optimization of the algorithm for subsets of these functions and on the implementation in a recursive architecture. Results of fixed-point simulations with different internal data formats and rounding schemes are presented. The design of evaluation tools for recursive CORDIC processors is also discussed.
