摘要
EPON是基于以太网技术的宽带接入,采用以太网的帧结构。文章详细介绍了EPON中CRC校验的原理和算法,给出了采用并行电路实现EPON中CRC产生和CRC校验的解决方案,然后用M odelsim进行了仿真。与串行电路相比,这种并行电路提高了CRC算法的实时性能,为进一步实现高速系统创造了条件。
EPON is a broad band link that is based in Ethernet and introduces the frame of Ethernet. The paper presents amply the principle and algorithm of CRC verification used in EPON,and gives the project about how to carry out the produce and verification in parallel, then simulates the circuit in Modelsim. Compare to the serial circuit,this circuit improves the real-time capability of CRC and sets up the condition for realizing high speed system.
