基于CPLD的电子琴系统设计

The organ system design based on CPLD

本文利用VHDL在Quartus II 7.2(32-Bit)环境下开发电子琴系统,核心是MAXII系列的EPM1270T144芯片。在传统CPLD芯片设计的电子琴基础上,本设计进行了扩展,增加了LCD显示模块和部分功能模块,使系统更为实用,但复杂度也相应的增加了,该系统主要由五大模块构成,分别由乐曲存储模块、发声模块、选择控制模块、液晶显示模块、LED显示模块。实现弹琴和演奏的基本功能,以及LED和LCD显示。

In this paper,VHDL in Quartus II 7.2(32-Bit) environment,developed under the organ systems,the core of MAXII family EPM1270T144 chips.In the traditional CPLD chip design based on the keyboard,the design of the extension,an increase of LCD display module and some functional modules,making the system more practical,LED display modules.To achieve the basic functions of playing music and playing,as well as LED and LCD display.
