基于SoC的千兆EPON ONU硬件平台的设计与实现

Design and implementation of Gigabit EPON ONU hardware platform based on SoC

利用Altera Cycl oneTM II芯片完成了符合IEEE802.3ah标准的千兆EPON ONU硬件平台的设计和开发,并基于SoC在FPGA中嵌入8051处理内核以完善整个ONU系统的OAM功能。该硬件平台根据EPON ONU功能和逻辑代码的实现方式,具有性能稳定、配置维护灵活的特点。

According to IEEE802.3ah standard, the design and implementation of gigabit ONU hardware platform is accomplished by using Altera Cyclone^TM Ⅱ FPGA, moreover, an 8051 core is embedded into FPGA to perfect OAM based on SoC. The hardware platform that is dependent on function of ONU, instruction of logical code and cost of ASIC manufacture, is provided with stable performance and flexible operation.
