:CORDIC算法将复杂的算术运算转化为简单的加法和移位操作,然后逐次逼近结果。这种方法很好的兼顾了精度、速度和硬件复杂度,它与VLSI技术的结合对DSP算法的硬件实现具有极大的意义,因而在数字信号处理领域得到了广泛应用。本文首先简要介绍了CORDIC算法的原理,然后详细描述了双模式(旋转/向量)CORDIC算法的预处理和后处理,并且基于FPGA实现了流水线双模CORDIC算法。-By converting complex arithmetic into simple operations such as adding and shift then gradually approach the exact result, CORDIC algorithm keeps balance between precision, speed and hardware complexity, and whose combination with VLSI performs a great role in the hardware implementation of DSP algorithm, enhance CORDIC has been widely used in the field of digital signal processing. We studied the principle of CORDIC algorithm, and described the pre and post process of dual mode CORDIC algorithm, then the pipelined dual-mode CORDIC algorithm is implemented based on FPGA.
