| Abstract: | Based on analyzing the principle of 8B/10B coding, an improved 8B/10B coding is designed, which can provide another real-time low-speed channel with encoding the high-speed data. Based on FPGA technology, the lookup table method is used to realize the circuit of the improved encoding and decoding. The effectiveness of the encoding scheme is verified by simulation, and the synthesis is carried out in Spartan6 series FPGA. The results show that this design takes up less FPGA logic resources, and the speed of encoding and decoding can reach hundreds of MB/s. |
