Abstract
A block encoder flexibly encodes K codes to produce an encoded data block. The block encoder receives an unformatted block of 10 Gigabit Media Independent Interface (XGMII) data. The unformatted block of data includes data and/or K characters, both of which can be located in any position of the unformatted block. The block encoder inserts data characters into a first set of slots of the encoded data block. The block encoder encodes K characters to produce corresponding encoded K characters. Each encoded K character includes a link field, a position field and a recoded value field. The encoded K characters are inserted into a second set of slots of the encoded data block. A synchronization header is attached to the encoded data block to distinguish control blocks from pure data blocks. The header and encoded data block are subsequently scrambled in preparation for transmission.
