基于CORDIC算法的快速NCO设计

A Rapid NCO Design Based on CORDIC Algorithm

NCO在软件无线电、数字信号处理等方面有着广泛的应用。函数发生器是NCO中的关键部分,通过FPGA流水线实现了CORDIC算法,可替代传统ROM查找表法。通过对Altera和Xilinx公司的FPGA进行仿真及综合,验证了该设计的正确性及可行性。

NCO has a wide range of applications on software-defined radio,digital signal processing.Function generator is a key part of NCO.The algorithm of CORDIC is achieved by FPGA pipeline,and it can alternative the traditional ROM look-up table method.The correctness and feasibility of this design is verified by simulate and synthesize the FPGA of Altera and Xilinx Company.
