Will be explained calculation method that is (to be described later in Level2) various algorithms to calculate the trigonometric function exists, using the algorithm of CORDIC (CO-ordinate Rotation Digital Computer) method among them. If you want to calculate in hardware complex arithmetic functions, CORDIC is a fixed-point algorithm charming. Only the sequence of shift and add operations simple, this algorithm, it is possible to calculate a wide range of mathematical functions.
