摘　　要：分析了当前市场上主流Ps／2键盘鼠标的工作协议，阐述了Ps／2接口键盘控制器的工作原理，采用verilog硬件描述语言完成键盘控制器的硬件编码，并在FPGA台完成了键盘和鼠标的功能验证，经过多种键盘和鼠标的混合测试，充分证明所实现的PS／2接口键盘控制器完全兼容市场上主流Ps／2接口的鼠标、键盘及驱动。Analyse the PS/2 protocol which is used by a great lot of keyboard and mouse on market,introduce the theory of PS/2 keyboard controller, implement the hardware code of the keyboard controller with the verilog language, and finish the functional validation of keyboard and mouse on a FPGA platform. It is proved sufficiently that the PS/2 keyboard controller is compatible with the majority keyboard and mouse with PS/2 interface.
