摘要
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 has been used to implement DSP algorithm extensively Because it can turn many complex operations into some simple addition and shift operations, which has very important significance in implementing DSP algorithm with hardware The implement of many complex and important algorithms has been came in true with it This paper firstly introduces the abstract of CORDIC algorithm Then, applications condition of CORDIC algorithm is discussed in home and abroad At last, The author explains a self-designed cordic-based parameterized FFT module
