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 calculations

The critically damped CORDIC algorithm for QR decomposition

TL;DR: The coordinate rotation digital computer (CORDIC) algorithm is an alternative solution to the traditional multiplication, division, and square root version of QR decomposition that converges faster than the conventional CORDIC algorithm with the penalty of storing all the scale factors in a ROM.
