| Abstract: | The encoding rule of 8B/10B and inherent relationship among 8B/10B codes are studied in this paper. A new implementing method of 8B/10B encoding and decoding is introduced, which combines the advantages of lookup-table and logic analysis methods with low computation complexity, easy synchronization, high speed and high reliability. The algorithm of encoding and decoding is described with Verilog HDL, and was simulated and synthesized with high performance FPGA. So the hardware circuit is realized to validate the feasibility of this method. The design of different high speed 8B/10B encoding and decoding module or IC is easily fulfilled with it. |
