摘　　要：与利用微处理器(CPU或MCU)来实现乐曲演奏相比,以纯硬件完成乐曲演奏电路的逻辑要复杂得多,如果不借助于功能强大的EDA工具和硬件描述语言,仅凭传统的数字逻辑技术,即使最简单的演奏电路也难以实现。本文重点介绍用杭州康芯电子有限公司生产的GW48系列EDA实验系统,利用数控分频器设计硬件乐曲演奏电路(电子琴),使读者初步了解VHDL硬件描述语言和Quartus II开发环境。compared with using CPU or MPU to play music, using complete hardware implementation to achieve playing music is much more complicated. It is very demanding to design even the most simplest player circuit just by using traditional digital logic technologies, without the help from a powerful EDA tool or hardware description language.？？In this paper, we introduce the GW48 serials EDA system from HongZhou KongXin electronic Inc, and explain how to design a music player circuit using a digital fre- quency multiplex system. The readers can get familiar with VHDL hardware description language and Quartus II developing environ- ment.
