In this paper, we introduce modifications on the classic CORDIC algorithm to reduce the number of iterations, and hence the rounding noise. The modified algorithm needs, at most, half the number of iterations to achieve the same accuracy as the classical one. The modifications are applicable to linear, circular and hyperbolic CORDIC in both vectoring and rotation modes. Simulations illustrate the effect of the new modifications.
