Design of DDS Based on Improved CORDIC Algorithm

Abstract

For the shortcomings that computation speed of the DDS decreases with iterations increasing in CORDIC algorithm., the traditional algorithm of multiple iterations is displaced by a point of decompose predict the direction of rotation and multi-level iterative parallel computing method in this paper. The function simulation results show that the improved algorithm enhance the computation speed and maintain data high precision. This design has high computing speed, high precision and simple hardware implementation etc.
