CORDIC算法被广泛应用于数字信号处理算法的硬件实现中。由于它将许多复杂的算术运算化成简单的加法和移位操作 ,因此它在许多 DSP算法的硬件实现中都有着极为重要的意义。有了它 ,许多难于实现而又极具应用价值的算术函数的硬件实现成为了可能。本文首先介绍了 CORDIC算法的理论概要 ,然后给出了 CORDIC算法在国内外的应用现状。最后 ,给出了作者自行设计的基于 CORDIC算法的可参数化的 FFT模型。 CORDIC algorithm is widely used in hardware implementation of digital signal processing algorithms. Because it converts many complex arithmetic operations into simple addition and shifting operations, it is of crucial importance in the hardware implementation of many DSP algorithms. With it, it is possible to implement many hard-to-implement and extremely valuable arithmetic functions. This paper first introduces the theoretical outline of CORDIC algorithm, and then gives the application status of CORDIC algorithm at home and abroad. Finally, a parametric FFT model based on CORDIC algorithm designed by the author is given.
