摘要
针对由ARM和FPGA组成的嵌入式千兆网数据传输系统的特点,提出了一种提高系统数据传输速度的方法。首先介绍了嵌入式数据传输系统的工作原理,然后对数据传输的效率和操作系统的TCP/IP协议栈工作流程进行了分析,在此基础上提出了对软硬件进行改进的方法,该方法既利用操作系统的网络协议栈,又发挥了FPGA并行处理的优势,大大提高了系统资源的使用效率和数据传输速度。
According to the characteristics of the embedded Cigabit Ethernet data transmission system composed by ARM and FPCA, a method of improving the data transmission speed is proposed. First, the working theory of the embedded data transmission system is introduced, and then the data transmission efficieney and the working flow of the TCP/IP protocol stack are analyzed. On the basis of that, a method of improving the hardware and software is proposed, which not only utilizes the network protocol stack of the operating system, but also plays the advantage of FPGA parallel processing data transmission speed.
