摘　　要：简述了ISD2560语音芯片和CPLD两种器件各自的特性.用CPLD作为ISD语音芯片的控制器,在EDA软件工具的支持下实现了公交车报站系统的设计.在分析语音芯片内部存储器结构的基础上,给出了语音段的划分和首地址的确定方法,为ISD语音芯片采用灵活的地址操作模式创造条件.系统将语音的录放集于一体,为使用者进行语音的录入和修改提供了方便.The characteristics of ISD2560＇s speech chip and the CPLD device are presented in the paper. Using the CPLD device as a controller of the speech chip and the bus auto-reporter-calling system design is achieved with the help of the EDA software tools. According to the analysis of speech CMOS chip＇s memory structure, it shows the way how to carve up the speech and how to arrange its beginning address, As a result, it is easy to operate the ISD Speech CMOS chip＇s addressing mode. In the system, the recording and playing function can be made together, so it is easy to record and play at the user＇s convenience,
