This electronic document is a “live” template and already defines The overview of this paper is to design a micro rotation selection block for TW based FFT. This design is mainly based on Adaptive CORDIC algorithm. CORDIC stands for COordinate Rotation DIgital Computer. Two ways to implement the CORDIC algorithm are 1.Vector mode and 2. Rotation mode. The main difference between Vector and rotation are, vector mode is used to compute an angles at given point where as Rotation mode is used to compute the sine and cosine terms at given point. This paper mainly deals with vector method by using micro rotation for complex multiplications in FFT architectures. Ɵi- selection (Ɵi- sel) block for CORDIC based Twiddle Factor (TW) architecture is a computation approach which does an angle selection. CORDIC algorithm is easy to implement trigonometric, hyperbolic and exponential functions based on micro rotation for VLSI Signal processing. The simulation results are examined using Xilinx ISE 14.5Tool.
