TLDR
This paper describes a single unified algorithm for the calculation of elementary functions including multiplication, division, sin, cos, tan, arctan, sinh, cosh, tanh, arCTanh, In, exp and square-root.Abstract:
This paper describes a single unified algorithm for the calculation of elementary functions including multiplication, division, sin, cos, tan, arctan, sinh, cosh, tanh, arctanh, In, exp and square-root The basis for the algorithm is coordinate rotation in a linear, circular, or hyperbolic coordinate system depending on which function is to be calculated The only operations required are shifting, adding, subtracting and the recall of prestored constants The limited domain of convergence of the algorithm is calculated, leading to a discussion of the modifications required to extend the domain for floating point calculationsread more

Modified CORDIC algorithm for computation of arctangent with variable iterations
Huijie Zhu,Yizhou Ge,Bin Jiang +2 more
TL;DR: The proposed CORIDC algorithm calculates the nearest predefined angle to the input phase at the beginning of every iteration and then rotates by an optimal angle and provides faster convergence speed that reduces the number of iterations with respect to the previous approaches.
