摘要
采用EDA工具设计了一个音乐发生器,该系统基于时钟分频器的原理及VHDL自顶向下设计方法来实现,按模块化方式进行设计。该系统可以通过拨码开关切换乐曲,实现乐曲的自动演奏。系统主要由5个模块组成:分频模块、乐曲选择模块、乐曲产生模块、音符译码模块和数控分频模块。
The system is a musical generator that is designed by powerful EDA tools. It is based on the principle of clock divider and the VHDL top - down design to achieve, according to modular design. This system can play music automatically, in which music is changed by DIP switch. It consists of the frequency separated module, the music selected module, the music generated module, the note decoded module and the numerical frequency separated module.
