基于CORDIC算法的高速ODDFS电路设计

High speed ODDFS circuit design based on CORDIC algorithm

为了满足现代高速通信中频率快速转换的需求,基于坐标旋转数字计算(CORDIC,Coordinate Rotation Digital Computer)算法完成正交直接数字频率合成(ODDFS,Orthogonal Direct Digital Frequency Synthesizer)电路设计方案。采用MATLAB和Xilinx System Generator开发工具搭建电路的系统模型,通过现场可编程门阵列(FPGA,Field Programmable Gate Array)完成电路的寄存器传输级(RTL,Register Transfer Level)验证,仿真结果表明电路设计具有很高的有效性和可行性。

In order to satisfy the requirement of frequency fast conversion in the modem high-speed communications,ODDFS circuit was designed based on CORDIC algorithm. Using MATLAB and Xilinx System Generator development tools to build the system model of the circuit,and finally complete RTL （Register Transfer Level）verification of the circuit by FPGA （Field Programmable Gate Array）. Simulation results prove effectiveness and feasibility of circuit design.
