CORDIC (digit-by-digit method, Volder's algorithm) (for COordinate Rotation DIgital Computer)'s a simple and efficient algorithm to calculate hyperbolic and trigonometric functions. It's commonly used when no hardware multiplier's available (for example, simple microcontrollers and FPGAs) as the only operations it requires are addition, subtraction, bitshift and table lookup. The modern CORDIC algorithm was first described in 1959 by Jack E. Volder. It was developed at the aeroelectronics depart… (More on Cordic)
