CORDIC (CO-ordinate Rotation DIgital Computer) algorithm was first introduced in the year the 1959 for the computation of trigonometric functions, multiplication, division, data type conversion, square root and logarithms. The speed of FFT can be improved by using CORDIC which dynamically calculates the trigonometric functions. These can be efficiently implemented using processing elements to perform vector rotations. CORDIC offers a method to calculate all the desired functions in a simple manner. Due to its simplicity of operations the CORDIC algorithm is well suited for VLSI implementation. The architecture and implementation of reconfigurable complex FFT is presented here.
