基于FPGA的乐曲自动演奏器的设计

Design of Automatical Music Player Based on QuartusⅡ

为了实现乐曲的自动演奏,可以采用Altera公司的FPGA硬件电路。在其开发平台QuartusII上,以硬件描述语言的系统层次的设计方法,通过数控分频器和LPM_ROM完成了乐曲自动演奏电路的设计,并进行仿真。仿真结果显示利用FP-GA可以灵活、高效地实现乐曲的自动演奏。

In order to realize the automatic music playing,altera＇s FPGA hardware circuitry can be used.On its development platform QuartusII,automatic music playing circuit design is completed through NC divider and LPM_ROM,using Hardware Description Language＇s system-level design approach,and simulation is executed.Simulation results show that the use of FPGA can achieve the automatic music playing flexibly and efficiently.
