摘　　要：　提出了一种基于CORDIC(COordinateRotationDIgitalComputer)算法的流水线型数控振荡器的实现方法。硬件描述语言的仿真与综合结果表明,采用这种方法设计的数控振荡器精度高、误差小、结构简单;与基于查找表的数控振荡器相比,更易于ASIC实现。The CORDIC (COordinate Rotation DIgital Computer) algorithm is described, and a method for implementing a numerically controlled oscillator (NCO) based on this algorithm is presented in the paper Results from simulation and synthesis indicate that the implementation has the advantages of high precision, low error and simple structure As compared with the NCO based on lookup table, it is easier for implementation in ASIC
