基于FPGA的异步串行通信控制器的设计与实现

本论文采用VHDL语言描述硬件功能，利用Altera公司的FPGA芯片；采用模块化设计方法设计UART（通用异步收发器）的各个模块，在QuartusII和ModelSim环境下进行设计、编译、仿真和下载。而上位机利用VC6.0实现PC机与UART的通信。最后的通信测试表明系统数据完全正确。

This paper described the hardware functions by VHDL and designed the UART modules in modularization method by using FPGA COMS chip of Altera company， which was designed， compiled， simulated and downloaded in QuartusII and ModelSim. However， upper machine used VC6.0 to realize the communication between PC and UART. The final simulation results show the system data is completed correct.
