| 摘 要： | 简要分析了当前语声IC开发存在的问题,并针对这些问题提出了一种基于DSP UART架构的语声IC开发系统方案。对UART(通用异步接受发送)器件TL16C550BN,语声IC———ISD4004等器件的特点做了简要介绍。在硬件电路设计部分,对如何通过TL16C550BN实现PC机与DSP之间的通信、SPI接口以及DSP与语声IC之间的接口电路均做了详细介绍。还对系统上、下位机软件的实现做了具体分析。利用本文介绍的语声IC开发系统对语声IC进行开发将更为便捷、灵活,具有较大的实用意义。

| Abstract: | This paper analyses problems in phonetic IC developing briefly at present,and puts forward a scheme for phonetic IC developing system based on DSP UART framework.Characteristics of UART(universal asynchronous receiver and transmitter)device TL16C550BN and Phonetic ICISD4004 are introduced briefly.The realization of communication between DSP and PC by using TL16C550BN,SPI interface and the hardware connections between TMS320VC5402 and ISD4004 are all introduced particularly in the hardware circuit design.In this paper,there is also a clear analysis for the software of the host computer and the slave system.This phonetic IC developing system will make the phonetic IC developing more convenient and flexible,so it really has a greater value in practical application. |
