摘　　要："龙腾R2"是西北工业大学自主设计的与PowerPC指令集兼容的32位嵌入式微处理器,为了提高"龙腾R2"SOC系统中人机交互能力,提出了利用"龙腾R2"中的键盘控制器在PS2键盘通信协议下与键盘进行通信的方法;首先分析了PS2键盘通信协议,然后给出了键盘驱动程序的结构以及在VxWorks的BSP(板级支持包)中如何对键盘驱动程序加载的原理,然后将VxWorks移植到龙腾R2微处理器原型验证平台中;经过长时间的应用和测试表明,在移植后的FPGA验证平台上,VxWorks操作系统可以稳定运行。＂Longtium R2＂ is a 32-bit embedded microprocessor, and its instruction set is compatible with PowerPC designed by Northwestern Polytechnical University.To enhance the ability of the communication between human and machine in ＂Longtium R2＂SOC system, expounds how to communicate between host and keyboard by using the i8042 keyboard conlToller in ＂Longtium R2＂.The PS2 keyboard communication protocol is analyzed, the structure of the keyboard driver and the method of Loading the keyboard driver in VxWorks BSP （board support package） are explained, then VxWorks is transplanted to the verification platform of＂Longtium R2＂. Based on the platform, the real-time operating system VxWorks which has been applied and tested for a long time runs steadily.
