摘要
把现场采集的海量数据可靠地传到远程的服务器上是论文的任务。在Xilinx FPGA上用PowerPC硬核、内存控制器和千兆网IP核构建SOPC系统。在PowerPC405上移植嵌入式Linux操作系统,实现了嵌入式千兆网数据传输。通过编程测试得出网络传输性能和数据包大小的关系。此外,设计了用户自定义接口逻辑IP核,以便能和采集模块高速通信并缓存。该系统的优点是体积小、数据带宽高、可靠,结果表明符合项目的要求。
The task of this paper is to transmit the data reliably from the local to remote server. A SOPC system with PowerPC hard core, memory controller and Gigabit Ethernet IP core is built in Xilinx FPGA. Data transmission with Gigabit Ethernet is achieved by the way that embedded linux is transplanted on PowerPC405. The relation between performance of the network and packet size is obtained by a test program. In addition, a custom IP cores was designed in order to communicate with the acquisition module in high speed and cache. The system has the advantage of small size, high bandwidth, reliability, in line with the requirements of the project.
