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

Architectural implementation of cordic unit and its applications
TL;DR: The proposed DDS design, which is based on pipelined CORDIC, has considerable improvement in terms of SFDR compared to other existing designs at reduced hardware and a multiplier-less architecture for the implementation of radix-2^2 folded pipelining complex FFT core based on CORDic technique is proposed.
