系统应用FPGA技术，通过VHDL编程，在CPLD上实现。电子琴的基本原理是产生各个音符对应的频率，将频率放大后驱动喇叭发出音响。该电子琴包括手动弹奏与自动演奏两种功能，其中手动弹奏时还可录音回放。文中叙述了电子琴的设计原理和分块实现的方法，详细介绍各模块的设计及模块之间的连接组合方法，还包括电子琴的使用说明。-System FPGA technology, the adoption of VHDL programming, to achieve in the CPLD. The basic principles of flower is the corresponding frequency of each note will be the frequency of enlarged issued after the driver speaker audio. Playing the organ, including manual and automatic playing two functions, which also play recordable playback manually. The paper describes the design of flower and block the realization of the principle of the method, details of the module design and module combination of the connection between the methods also include the use of electric piano note.
