CORDIC (for COordinate Rotation DIgital Computer), also known as Volder's algorithm, is a simple and efficient algorithm to calculate hyperbolic and trigonometric functions, typically converging with one digit (or bit) per iteration.
CORDIC algorithms are mainly designed to implement basic transcendental functions (Sine, Cosine, etc.) efficiently. They will not allow you to do anything more than what these standard functions, already available on every platform, already do.
However, if you are interested in knowing how these algorithms work and how to implement them, see the following link:
