摘　　要：本文介绍了一个基于TMS320C54x系列数字信号处理器(DigitalSignalProcessor,简称DSP)的语音采集系统,并探讨了此系列数字信号处理器的几种与外部模块进行通信的方法。实验证明使用EXAR公司的UART芯片ST16C550让DSP与外部进行通信编程方便,简单实用,而且系统运行稳定可靠,实用性好。In this paper, a speech collecting system which runs on TMS320C54x digital signal processor (DSP) is described. Several communication Methods between this series of DSPs and other peripheral equipments are also explored and presented here. The experimental results shows that using UART processor (ST16C550) is not only the simplest communication method, but also a feasible and effective approach. The system runs smoothly without any problems occured for two weeks which is our first test period.
