本文详细阐述了利用VHDL语言和模块化的设计方法,在EDA开发工具QuartusⅡ软件平台上,通过音符编码的设计思想实现了音乐自动播放、琴键演奏、配有随音乐节奏而闪烁变化的LED以及乐谱显示等功能的乐曲演奏器系统。使基于FPGA芯片的乐曲演奏器数字电路得到了优化,提高了它的灵活性和可扩展性。 This paper elaborates the VHDL language and modular design method. On the Quartus II software platform of EDA development tool, it realizes automatic music playing, key performance, LED with flickering changes according to the rhythm of music and music score Display and other functions of the music player system. So that based on the FPGA chip music player digital circuit has been optimized to enhance its flexibility and scalability.
