Implementation of the Parallel Algorithm of CRC Check Codes in EPON

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.
