基于CPLD的MIDI音乐播放器的设计

The design of MIDI music player based on CPLD

本音乐播放器依据MIDI音乐基本原理,结合EDA技术,采用ALTERA公司的可编程逻辑器件(CPLD)EPF10LC84-4作为控制核心而设计的。本文主要阐述了利用VHDL语言设计MIDI音乐发生器芯片,再配上必要的外围电路,从而实现四首音乐选择播放、并配有随音乐节奏而闪烁变化的彩灯等功能的EDA应用系统。

The MIDI music player is designed according to the basic principle of music, combining EDA technique, and using the Complex Programmable Logic Device（CPLD） EPF10LC84-4 chip which is produced by ALTERA company. The thesis introduce how to use the music player chip and the necessary outer circuit to complete an EDA system which can play four pieces of music and have the colorful lights flicking with the music rhythm.
