| Abstract: | 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. |
