摘　　要：分析了乐曲演奏设计中音符、频率、节拍、显示与编码的相互关系,并在EDA开发工具QuartusⅡ平台上,采用VHDL语言层次化和模块化的设计方法,通过音符编码的设计思想,实现了基于FPGA片上系统(SoC)动态显示乐曲演奏器的设计,使乐曲演奏数字电路设计得到了更好的优化,同时减少了设计芯片的数量、缩小了体积、降低了功耗、提高了设计的灵活性、可靠性和可扩展性。This paper analyzes the correlation between the coding with the note, frequency and rhythm in musical performance. Based on Quartus Ⅱ- the EDA development tool, this design has adopted the method of classification of VHDL and modulization. Through the concept of note coding,the design of dynamic displayfing music player has been achieved on the basic of FPGA,a System on a Chip（SoC）. The design has improved the music displaying digital circuit and reduced the quantity of designing chip. Having more narrow volume and less consumption, the design has improved the flexibility, dependability and expansibility as well.
