Implementation of on FPGA Based on CORDIC Algorithm

Based on the introduction of the principles of the traditional Direct Digital frequency Synthesizer and CORDIC algorithm,the problem on how to choose the algorithm parameter is analyzed by detailed derivation.Then this paper describes a high-speed trigonometric signal generator with the parallel pipelined architecture of CORDIC.The study of Quartus compilation and Modelsim simulation shows the advantage with high clock frequency of 205 MHz and lower calculation errors of 10-5.Finally,the implementation process on FPGA and the results of software simulation and hardware application were presented.
