摘要
为了实现PC机同时与多个外设终端实时进行通信显示的要求,从而达到PC机对所属串口设备的实时监测与控制,本文采用基于FPGA和Ni OSⅡ软核的方法开发出一套多串口通信系统。文章通过以CycloneⅡ系列的EP2C8Q208C8N为MCU设计电路和Verilog语言描述生成UART IP软核实现多串口数据传输至处理器的设计方案,结合Model Sim仿真以及串口调试助手模拟PC机与串口设备之间通信的试验。结果表明,该系统能实现PC机与所属串口设备之间的通信,通信准确率高,速度快,具有可行性。
In order to achieve the computer simultaneously with multiple peripheral terminal display real-time communication requirements, so as to achieve the real-time monitoring and control between the computerand its serial equipments.Based on FPGA and Ni OS Ⅱ soft core, this paper developed a serial communication system. The article using the Cyclone Ⅱ series＇ EP2C8Q208C8 N for the MCU circuit＇s design and Verilog language to describe the generation UART IP soft-core to achieve the Multi-serial data transmission design. Combined with Model Simsoftware＇ssimulation and serial debugging assistantsimulation communication between computer and serial devices. The results show that the system can achieve communication between computer and its serial equipments, the communication is High accuracy and speedy, and the system has feasibility.
