| Abstract: | 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. |
| Keywords: | FPGA SOPC custom IP core embedded Linux gigabit network |
