基于FPGA的CORDIC算法的分析和实现

The Analysis and Implementation of CORDIC Algorithm Based on FPGA

该文分析了CORDIC算法为作为硬件实现基本的运算的方法,实现了开方、正弦、余弦、乘法、除法、正切、反正切,和一些双曲函数的实现。提供了一种基于流线设计的CORDIC算法的实现,在每层流水线上都可实现6种计算,共用一个加法器。减少了硬件内部资源的使用。通过是实现的结果可以看到计算结果在水线级数STAGE＋3个CLK信号后实现了连续的实时计算结果。

This paper analyzed the CORDIC algorithm for hardware implementation of basic operation method, realized the root, sine, cosine, multiplication, division, tangent, inverse tangent, and some hyperbolic function. Provide a method based on pipeline design CORDIC algorithm, each line can be realized 6 kinds of calculation, sharing one adder. Reducing the hardware resource use. Is to achieve the results you can see through calculation results in line series STAGE＋3 CLK signal after achieving a continuous real-time calculation results.
