Based on analyzing the encoding theory, inherent coherence and logic relationship of 8 B/10 B code, a novel implementing method of 8 B/10 B encoding is proposed. The frequency of encoding can be improved by using the pipelined processing, some groups of data have to be encoded under the one clock. The experimental results show that the proposed 8 B/10 B encoder can achieve the function of coding, and the frequency of coding can reach 500 MHz. The proposed8 B/10 B coder can be used to the high speed serial i...
