Abstract: CORDIC stands for Coordinate Rotation Digital Computer. The CORDIC algorithm was introduced for the computation of Trigonometric functions, Multiplication, Division, Data type conversion, Square Root and Logarithms. It is a highly efficient, low complexity, hardware efficient algorithm giving a robust technique to compute the elementary functions. In the paper the CORDIC algorithm, its usage in calculating quadrature functions, its applications and advantages and disadvantages are explained.

Keywords: CORDIC (Coordinate Rotation Digital Computer), Sine-Cosine, CORDIC Algorithm.
