| 摘 要： | 介绍了一种基于FPGA和双端口RAM的DDS任意波形发生器的实现方法。该系统使用单片机作为主控器,完成用户接口的处理和协调控制的功能,FPGA在实现了DDS中的累加器的功能的同时也集成了单片机的外围接口电路,双口RAM的引入使得在单片机向其写入数据的同时,FPGA可进行扫描输出,加快了系统速度。同时给出了在Proteus和Matlab下的仿真结果。

| Abstract: | The way to realize an arbitrary waveform generator with FPGA and DDS are discussed in this paper- The microcomputer is the master controller in this system, it can accomplish the disposal and control of the user interface. The FPGA integrate the periphery interface circuit, it can realized the function of Accumulator. The FPGA can export scanning when the microcomputer is writing to the RAM by use the dual port RAM, therefore the system is to become more rapid. The simulation results are given by using the Proteus and Matlab at the same time. |
