Most of the hardware algorithms exist to handle the hardware intensive signal processing problems. Among these algorithms is a set of shift-add algorithms collectively known as CORDIC for computing a wide range of functions including certain trigonometric, hyperbolic and logarithmic functions. Apart from this it can handle linear functions. Even though numerous papers covering various aspects of CORDIC algorithms, very few surveys concentrate on implementation in FPGAs. CORDIC (COordinate Rotation DIgital Computer) is an algorithm for computing transcendental functions like sine, cosine and arctangent.
