基于SoPC/NIOS Ⅱ的信号发生器设计与实现

摘要

This designation uses the SoPC technology based on embedded processor of NIOS Ⅱ, and designs an arbitrary waveform generator,which can not only output sine waveforms, square waveforms, triangle waveforms, sawtooth waveforms and other common waveforms, but also the frequency and amplitude of waveform is adjustable, and in system programming according to user's requirements, It has advantages of easy control, stable output frequency, high quality waveform and wide bandwidth.%运用基于NIOS Ⅱ嵌入式处理器的SoPC技术,设计了一个任意信号发生器,不仅可以输出正弦波、方波、三角波和锯齿波等常见波形,且各波形的频率和幅度可调,可根据用户需要进行现场编程,具有控制灵活、输出频率稳定、准确、波形质量好和输出频率范围宽等优点.
