本文在仿真的环境下利用可寻址的语音芯片和CPLD(复杂可编程逻辑器件)，设计一款实用，便携的专用语音播放器。 论文首先对本课题所要研究的问题做初步的分析，介绍其背景并对其意义和实际价值做了分析。根据太极拳口令的特点，确定了用CPLD控制低成本、播放时间较短的语音播放芯片的实现方案。根据方案要求，选择了美国华邦电子有限公司研制的可寻址的ISD(Information Storage Device)语音芯片ISD2590，并在详细了解ISD2590内部结构及逻辑关系的基础上，并对CPLD做一些基本的介绍。在这些基础之上，重点讲解和分析如何设计一个CPLD电路可以控制语音芯片使其实现要求的播放功能并且给出该电路的仿真结果。 用CPLD来实现语音芯片的播放功能，重点是根据理想中所要求的时序电路来设计一个CPLD器件，使它的输出信号恰好达到要求的语音芯片的输入信号进而可以控制语音芯片的播放。

This paper uses address searchable COMS chip and CPLD(Complex Programmable Logic Device)which is under emulational environment. The aim is to design a specified chiplike record/play device which is practical and portable. The paper first makes an elementary analysis of the problem which is needed to be solved in the subject, then make a general description of the its background, value and signification. It chooses the project which uses CPLD to control the cheap and short play-time CMOS chip. This paper not only introduced the interior structure and characters about ISD2590(produced by Winbond Electronics Corporation America) that is chose according to the subject, but also gives a basal description of CPLD.Based on this, The emphasis on the subject is to design a CPLD controlling the CMOS chip to achieve the function and to give a emulational result of the circuitry. In order to achieve the function of the chip, the aim is to design a CPLD whose output can be compared with the input of the CMOS chip due to the required schedular circuit diagram.
