| 摘 要： | 高速数字信号处理芯片(DSP)在鱼雷数字信号处理领域得到了广泛的应用,在这类器件中,大部分没有异步通信串口,使得它和低速设备的通信受到限制。文中介绍了ADSP-21160数字信号处理芯片和TL16C752B两路通用异步接收/发送器(UART)接口芯片的功能,给出了ADSP-21160通过TL16C752B与全雷管理中心、系统检查台进行异步串口通信的硬件连接电路原理图,设计了UART初始化软件和查询方式读/写数据流程,解决了高速DSP和全雷管理中心、系统检查台低速设备通过异步串口通信的问题。

| Abstract: | With the development of modern torpedo technology,high speed digital signal processor(DSP) has been widely used for signal process.However,the communication between most DSPs and low speed peripherals was restricted since the lack of asynchronous communication serial port.This paper introduces ADSP-21160 chip and TL16C752B,a universal asynchronous receiver/transmitter(UART) interface chip.The ADSP-21160 communicates with the whole torpedo control center and the system tester via TL16C752B,and the principle diagram of hardware circuit for asynchronous serial port communication is presented in detail.UART initialization software is designed and W/R data flow is realized in inquire mode.Therefore,the problem in communication between high-speed DSP and low-speed peripherals in the whole torpedo control center and system tester through asynchronous serial port is solved completely. |
