基于FPGA的音乐硬件演奏电路设计与实现

摘要

In this paper, the EDA development platform, NC divider circuit using VHDL language design, programmable logic device CPLD/FPGA overall analysis, modular analysis, simulation analysis of the overall module three steps to the song "Butterfly Lovers"example, the hardware implementation of the overall reset button to select the play mode, Loops and digital tube display sheet music functions. The system can automatically start from scratch loop can also start and stop at any time, the button to select the playback loop playback switch songs and dynamic display of light-emitting diodes play notes. Verified after the actual circuit testing met the design requirements.%该文在EDA开发平台上,利用VHDL语言设计数控分频器电路,采用可编程逻辑器件CPLD/FPGA,经过整体分析、模块化分析、整体与模块的仿真分析三个步骤,以乐曲《梁祝》为例,使硬件实现了整体复位、按键选择演奏方式、循环演奏以及数码管显示乐谱的功能.系统能自动从头开始循环播放,也可随时起停、、按键选择播放、循环播放播放中切换歌曲以及发光二极管动态显示播放的音符.经过实际电路测试验证,达到了设计要求.
