基于FPGA串口通信系统设计

基于 FPGA 串口通信系统设计摘要:UART(即 Universal Asynchronous Receiver Transmitter）是数据通信及控制中广泛使用的一种全双工串行数据传输协议。本设计基于 FPGA 器件实现对 UART 的波特率产生器、UART 发送器和接收器及其整合电路的模块化设计，采纳 Verilog HDL 语言对三个功能模块进行硬件描述。通过串口调试助手进行验证，其结果完全符合 UART 协议的要求和预期的结果.关键词:UART ; FPGA ; Verilog HDL ; 验证Based on FPGA serial port communications system designAbstract：UART （i。e。 Universal Asynchronous Receiver Transmitter) is in the data communication and the control the widespread use one kind of full—duplex serial data transmission agreement. This design realizes based on the FPGA component to the UART baudrate producer, the UART transmitter and the receiver and the conformity electric circuit's modular design， uses Verilog the HDL language to carry on the hardware description to three functional modules. Debugs the assistant through the serial port to carry on the confirmation, its result meets。Key words：UART， FPGA , Verilog HDL , Validate目 录第一章 绪 论................................................11.1 课题背景...............................................11.2 现场可编程门阵列 FPGA.................................11.2 Verilog HDL 简介.......................................3第二章 串行通信系统...........................................52。1 概述..................................................52。2 通信简述..............................................52.2。1 串行通信概念.....................................62。3 RS-232C 总线..........................................72。3.1 RS—232C 接口特性................................82.4 串行通信接口组成.......................................92。5 UART 通信协议.......................................102。6 系统整体结构.........................................12第三章 UART 系统设计............
