Abstract |
|
In this paper, we proposed an efficient radix-2 FFT architecture using CORDIC algorithm for FPGA implementation of FFT. CORDIC algorithm is used for twiddle factor multiplication; it will reduce the computation time and make faster processor. The proposed algorithm uses a new addressing scheme and the angle generator logic in order to remove the ROM usage to store twiddle factors. The CORDIC algorithm offers opportunity to calculate all the functions in a simple and elegant fashion. By using only additions and shift operations CORDIC algorithm calculates the rotation of a vector and it is an iterative algorithm. The design architecture is written in verilog HDL code using Modelsim and XILINX ISE 14.2 tools. |
