摘要 分析了CORDIC算法的基本原理和MVR-CODIC算法的特点。在此基础上,提出了一种改进型MVR-CODIC算法,利用查ROM表代替原算法中比例因子的计算方法,讨论了改进后算法的所需ROM表的容量,给出了实现框图。实验证明,改进型MVR-CODIC算法更适合于用大规模集成电路实现。 This article introduces the basic principle of the Coordinate Rotation Digital Compute (CORDIC) algorithm and key feature of modified Vector Rotational CORDIC (MVR-CORIDC) algorithm. A new algorithm is presented which is base on MVR-CORDIC algorithm. The modified MVR-CORDIC algorithm makes use of the searching ROM table to calculate scaling factor instead of original method in MVR-CORDIC algorithm. This paper analyses capacity of ROM table of modified MVR-CORIDC algorithm, further more a detail implementation frame is given. The experiment result shows that the modified MVR-CORDIC algorithm is more suitable than original algorithm in realization with very large scale integration.
