摘　　要：串口驱动程序由于涉及硬件寄存器较少,所以是外围器件驱动程序编写中相对较为容易的一类,但其与内核操作系统的联系上和其它驱动程序都具有相同的层次结构。论文着重阐述了vxWorks操作系统下串口驱动程序与其上层虚拟驱动层的交互,并详细解释了虚拟驱动层和串口驱动程序的功能以及初始化过程。论文最后结合代码示例给出了串口驱动程序的架构。Serial I/O Driver is relatively simpler than other peripheral drivers for its corresponding less register operations,but from the view of architectural relationship with kernel,it has the same organization with those other drivers.This paper firstly expounds the contacts between serial driver level and upper virtual driver level,and then in detail explains the functions of these two levels and their corresponding initialization processes.At last,the paper,combining with concrete codes,gives the architecture of a serial driver.
