皖西学院毕业论文设计第 1页简易电子琴的设计学生姓名:王春指导老师:郑大腾摘要本系统是采用 EDA 技术设计的一个简易的八音符电子琴,该系统基于计算机中时钟分频器的原理,采用自顶向下的设计方法来实现,它可以通过按键输入来控制音响。多功能电子琴的设计是在原有普通电子琴的基础上进行扩充的一个设计。该电子琴的设计大体可以由三个模块构成,分别是电子琴发声模块、存储器模块和选择控制模块。用超高速硬件描述语言 VHDL 编程可以实现各个模块的功能。不仅能实现弹琴和演奏的功能,它还能实现“复读”的功能,就是可以存储任意一段音乐,并且可以即时的播放出来。系统实现是用硬件描述语言 VHD L 按照模块化方式进行设计,然后进行编程、时序仿真、总体整合。本系统的功能比较齐全,有一定的现实使用的价值。本文中介绍了电子琴系统的整体的设计, 并基于超高速硬件描述语言 VHDL 在相关的芯片上编程实现的。关键字电子琴; EDA ; VHDL ;音调发生; 现场可编程逻辑器件 FPGA ;超高速硬件描述语言 VHDL ;电子琴系统; Abstract This system is designed using EDA technology a simple eight-note keyboard, the system clock divider based on the principle of puter, using top-down design methodology to implement, it can be controlled through the key input audio. Multi-function keyboard is designed to be an ordinary keyboard in the original expansion on the basis ofa design. The design of the keyboard in general consists of three modules, namely the keyboard sound 皖西学院毕业论文设计第 2页 modules, memory modules and select the control module. Ultra high-speed hardware description language VHDL programming function of each module. Not only can realize the function of playing and playing, it can achieve "repeat" function, which can store any piece of music, and real-time play out. System implementation is to use hardware description language VHDL modular way by design, then programming, timing simulation, integration. The system features a plete, there isa certain value. This paper introduces the overall design of the keyboard system, and based on high speed hardware description language VHDL in Xilinx's Spartan Ⅱ series 2sc200PQ208-5 chip programming.
