| 摘 要： | 根据IEEE802.3-2005和IEEE802.3ae标准,在Xilinx公司的Virtex6系列XC6VHX255T器件上设计实现了万兆以太网MAC层控制器。与千兆以太网相比,万兆以太网使用更宽的数据位宽和更高的时钟频率,这使得其MAC层控制器的设计和实现都面临新的挑战。在解决了数据并行处理、不定长字节CRC编码/校验及与千兆以太网兼容等问题的基础上,设计实现了万兆以太网MAC层控制器。经布局布线后仿真验证,说明该设计可满足万兆以太网实际应用的要求。

| Abstract: | A 10-Gigabit Ethemet MAC controller is designed to the specifications of IEEE802.3-2005 and IEEE802.3ae by using a Xilinx XC6VHX255T device which belongs to the Virtex-6 device family. Compared with the 1-Gigabit Ethernet, 10-Gigabit Ethernet uses wider bit wide and higher frequency, which brings new difficulties to its design and implementation. A 10-Gigabit Ethernet MAC controller is designed on the base of solving the problem of parallel data processing, unfixed width CRC and compatibility with 1-Gigabit Ethemet. The results of post-place and route simulation indicate that the design can meet the needs of 10-Gigabit Ethernet. |
