RS232通讯模块(UART)的设计RS232通讯模块(UART)的设计 摘要 介绍了通用异步收发器(UART)的原理,并以可编程逻辑器件FPGA为核心控制部件,基于超高速硬件描述语言VHDL在Xilinx公司的SpartanⅡ系列的2sc200PQ208-5芯片上编程完成UART的设计。经测试,该设计完全达到了设计要求。 关键词 通用异步收发器 可编程逻辑器件FPGA 状态机 Design of Communication Module in RS232Abstract The principle of Universal Asynchronous Receiver Transmitter isintroduced in this article. The programmable logic device of FPGA is thecore controller unit of the design. The design of UART will be achieved inthe 2sc200PQ208-5 chip of Xilinx corporation by programming with theVHDL(Very High-speed Description Language). And the design settles for therequirement. Keywords UART CPLD/FPGA State machine 设计任务和设计要求用VHDL设计RS232通讯的接口模块UART。 第1章 系统设计……
