摘　　要：在针对国防工业、导航、通信等领域中,广泛使用串行接口UART与外围设备进行通信。提出了一种基于PCI总线的8路异步传输标准的设计方案,该方案采用专用芯片XR17D158作为从设备挂接在MPC8280的PCI总线,实现PCI-232接口的硬件结构方案,并在VxWorks系统下开发设备驱动程序。本文重点分析了所用芯片的功能、硬件设计、寄存器配置,并给出了VxWorks操作系统下驱动程序的具体实现方法。In the field of defense industry,navigation,communication,power and so on,it widely uses serial interface Universal Asynchronous Receiver/Transmitter(UART)to communicate with peripheral equipment.This paper presents a design plan for 8 asynchronous transmission standard based on PCI bus,which adopts the special chip xr17d158 as a slave device mount to peripheral component interconnect(PCI)bus of MPC8280,acieve the hardware structure scheme of the PCI-232 interface,and develops the device driver in the VxWorks system.This paper focuses on the function,hardware design,register configuration of the used chip,and gives the implementation method of the driver in the VxWorks operating system.
