Abstract

The CORDIC algorithm principle is introduced in this paper,and a general modulator based on CORDIC algorithm for computing the sine value is designed.The system is structured and simulated by MATLAB/Simulink DSPBuilder and Quartus II. The simulation result shows the CORDIC algorithm can reduce hardware circuit and chip area.The feasibility of the structure to general modulator is proved.
