摘　　要：在卫星通信系统的信道加密业务中,通常使用FPGA的UART通信实现CPU与保密机之间的交互。文章介绍的UART通信模块,是一种新颖的串口发送和接收的FPGA设计,仅由Verilog中简单的always块就能实现,证明此方法的操作简单且实用性强。仿真测试验证收发模块可实现可靠的全双工串口通信,更容易满足实际设计的需求。In the channel encryption service of satellite communication system,UART communication of FPGA is usually used to realize the interaction between CPU and secret machine.The UART communication module introduced in this paper is a novel FPGA design of serial port sending and receiving,which can be realized only by a simple always block in Verilog.It proves that this method is simple and practical.Simulation test shows that the transceiver module can achieve reliable full duplex serial communication,which is easier to meet the actual design requirements.
