A PS/2 keyboard system is disclosed, wherein the VHDL compiler executed in the programmable logic array chip on FPGA module is used to convert the keyboard signal inputted from the keyboard into the corresponding command executable on the host computer, so as to control the host computer. Its main feature is to proceed self-diagnosis onto the command transmitted by the host computer for reducing the occurrence of errors, and actually realize the handshaking processing of the security data between it and the host computer. Since it has the characteristic to process signal synchronously by hardware, the disclosed keyboard system can greatly reduce the complexity of system design, increase the stability of system operation, and become easy for maintenance.
