Modified MVR-CORDIC Algorithm Research

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.
