摘要

介绍了CORDIC算法的基本原理

分析了CORDIC算法的具体计算方法.针对利用CORDIC流水线实现FFT蝶形运算耗费资源多的问题

依据CORDIC计算迭代系数的方法改进了CORDIC流水线的结构形式

使其适应FFT算法.整个FFT处理器的实现主要利用了Cyclone Ⅱ系列的EP2C35F672C6.并通过时序仿真和硬件仿真来进行比较.它们的计算结果基本一致.

Abstract

Introduces the basic principle of CORDIC algorithm

and analyses the calculation method of CORDIC algorithm.For use of CORDIC streamline realize FFT wing operation cost more resources problems

according to CORDIC iterative method of calculating coefficient to improve CORDIC pipeline structure form

in order to accommodate FFT algorithm.Choose ALTERA company Cyclone Ⅱ series of EP2C35F672C6 to realize the whole FFT processor.And timing simulation and hardware emulation are designed.Through comparing the both

the calculation results are basically the same.
