CORDIC算法硬件电路实现及改进

摘要

文章提出了一种新的基于CORDIC算法的硬件电路实现方法。首先介绍CORDIC算法及其原理，然后介绍了CORDIC算法的16级流水线结构硬件电路实现，最后介绍了一种新的改进型实现方法，可以有效在兼顾16级流水线结构的高实时性优点的同时，解决CORDIC算法本身对角度范围的限制问题，同时在某种意义上也降低了电路的复杂度。%The article proposes a new hardware circuit realization method based on CORDIC algorithm. First, it introduces the CORDIC algorithm and its principle. Then it presents the hardware circuit implementation of the CORDIC algorithm using 16 level pipeline structure. At last it recommends a new better method, which can include the high real-time performance and at the same time solve the limits on angle range of CORDIC algorithm. And it also reduces the complexity of the circuit in a certain sense.
