摘要
介绍如何利用CORDIC(Coordination Rotation Digital Computer)算法产生正余弦信号的实现过程基础上,研究并在FPGA中实现了基于流水线CORDIC算法的数控振荡器。仿真验证结果表明,该方法较之其它方法具有精度高、结构简单易于实现、节省资源且功耗低等特点,非常适合应用于高速高精度数字调制解调。
Based on introducing how to generate sine and cosine signal with a CORDIC （Coordination Rotation Digital Computer） algorithm, this paper studied and implemented Numerically Controlled Oscillator （NCO） with the pipelined CORDIC algorithm on FPGA （Field Programmable Gate Array）. Simulation results indicated that this method has characteristics of high accuracy, simple structure and easy to implement, saving resources and low power consumption and so on, is very suitable to apply in the high speed and high accuracy digital modulation and demodulation
