基于单片机和FPGA的任意频率发生器设计

A Design of Arbitrary Frequency Generator Based on MCU and FPGA

本文提出了一种基于直接数字频率合成(DDS)技术的任意波形发生器。在单片机和FPGA的控制下,将存储在FPGA的RAM中的数据按照一定规律取出,并经D/A转换器输出模拟波形。这种方法充分利用了FPGA的内部硬件资源,大大提高了产生波形的精度和频率范围。

This paper presents an arbitrary waveform generator based on DDS. Under the control of the MCU and FPGA, the data has been stored in the RAM of FPGA will be took out in certain order, and then analog waveform will be exported through D / A converter. This method makes full use of the FPGA＇s internal hardware resources, and greatly improves accuracy and frequency range of the waveform
