CORDIC (Coordinate Rotation Digital Computer) is an algorithm for computing transcendental
functions like sine, cosine and arctangent. The method can also be easily extended to compute square
roots as well as hyperbolic functions.
The algorithm works by reducing the calculation into a number of micro-rotations for which the
arctangent value is precomputed and loaded in a table. This method reduces the computation to
functions like sine, cosine and arctangent. The method can also be easily extended to compute square
roots as well as hyperbolic functions.
The algorithm works by reducing the calculation into a number of micro-rotations for which the
arctangent value is precomputed and loaded in a table. This method reduces the computation to
addition, subtraction, compares, and shifts. All functions easily performed by FPGAs.
