摘　　要：数控振荡器在数字信号处理中有着广泛的应用。本文研究并实现了基于CORDIC算法的流水线型数控振荡器。仿真和验证结果表明,该方法较之查找表法精度高,且结构简单、耗费资源少,非常易于FPGA实现。Based on CORDIC algorithm, a method for implementing a numerically controlled oscillator is described in the paper. In contrast with the NCO based on look-up table, results from simulation and synthesis indicate that this implementation has the advantages of high precision, simple structure and much less resource consumption. It is easier for implementation in FPGA.
