【摘要】：传统多串口并行通信数据传输系统无法自主获取串口号,需手动选择再打开串口,需要使用者事先了解接口编码,这无形增加了系统的工作时间。为此,设计一种基于FPGA的多串口并行通信数据传输系统,该系统中的串口数据接收模块采集多串口数据,并通过控制寄存器达到控制通信数据波特率的目的。系统利用NiosⅡ处理器使8种信道共同进行传输工作,其将数据传输到并串转换模块。并串转换模块对输出的8位并行数据添加通道标识、并串转换处理,再将处理后的并行数据传递到串口输出选择模块中。依据数据脉冲上升沿设计串口输出选择模块,该模块通过多路分配器将有数据通道的数据串行逐位送出。系统在软件中进行了传输设计、NiosⅡ处理器流程设计以及通信设备类的设计与封装。实验结果表明,所设计系统在FPGA上正确实现了8个串口数据的传输,并且具有较高的数据接收成功率。
[Abstract]:The traditional multi-serial port parallel communication data transmission system can not obtain serial number independently, and needs to manually select and open serial port, which requires the user to know the interface code in advance, which increases the working time of the system intangibly. For this reason, a multi-serial port parallel communication data transmission system based on FPGA is designed. The serial port data receiving module in the system collects multi-serial port data and achieves the purpose of controlling the baud rate of communication data through the control register. The system uses Nios 鈪，
