摘　　要：UART作为RS232协议的控制接口得到了广泛的应用,将UART的功能集成在FPGA芯片中,可使整个系统更为灵活、紧凑,减小整个电路的体积,提高系统的可靠性和稳定性。提出了一种基于FPGA的UART的实现方法,具体描述了发送、接收等模块的设计,恰当使用了有限状态机,实现了FPGA片上UART的设计,给出了仿真结果。UART is a widely used serial data communication interface, and mainly used in communication between device with RS232 interface. The general UART chip has several disadvantages, and to design it in FPGA can make system more compact, flexible, reliable and stable. A design method of UART based on FPGA is proposed, using finite state machine appropriately, Design of UART on FPGA is imple-mented, Finally, simulation of transmitting and receiving are provided.
