摘　　要：研究了一种基于查找表和CORDIC(Coordinate Rotation Digital Computer)算法相结合的数控振荡器(NCO)的实现方法,与仅基于查找表的方法相比,该方法结构简单、精度高、耗费资源少。仿真和验证结果表明,该设计是可行的,并易于FPGA实现。Based on look-up table and CORDIC （Coordinate Rotation Digital Computer） algorithm, a method for implementing a numerically controlled oscillator （NCO） is described in the paper. In contrast with the NCO based only on look-up table, its advantages are high precision, simple structure and much less resource consumption. Simulation and test results show that the design is feasible and easy to implement in FPGA.
