| Abstract: | CRC(Cyclic Redundancy Check) is the key mechanism in EoS(Ethernet over SDH) system.EoS(Ethernet over SDH) technology combines both advantages of SDH and Ethernet and realizes the Ethernet data on the SDH transmission.According to the hardware resources optimization and the characteristics of the CRC-16 check code algorithm for GFP frame length(PLI),the improving method based on FPGA,through the circuit simulation was put forward and the comprehensive results show that this method is realized with high-speed... |
