Abstract
Systems and methods for encoding/decoding a data word using an 8b/9b encoding scheme that eliminates two-aggressor crosstalk are disclosed. The 8b/9b encoding scheme enables a data word to be encoded using code words. Each of the valid code words does not include any three consecutive bits having a logic level of logic-high (i.e., '1'), and represent transition vectors for consecutive symbols transmitted over the high speed parallel bus. An encoder and corresponding decoder are disclosed for implementing the 8b/9b encoding scheme. In one embodiment, the encoder/decoder implements a modified Fibonacci sequence algorithm. In another embodiment, the encoder/decoder implements a look-up table.
