MB810 encoder/decoder, dual mode encoder/decoder, and MB810 code generating method

摘要

The MB810 encoder / decoder, a dual-mode encoder / decoder, and MB810 code generation method is disclosed. MB810 code generation method according to the invention, (a) a binary digital sum variance and alternating sum in the form of a 12 state points 4 × 3 matrix on a state transition consisting of a variance stack for generating a 10-bit code from the 8-bit data forming that consists of; (B) outputting a 10-bit code at a given point state constituting the matrix; (C) selecting a code of forming a pair complement from a set of code that can reach the state point constituting the matrix; And (d) complement pair to compensate for the non-existent state point in the code which forms the selected code to form an 12 point state; (E) selecting a control code including the IDLE code among the codes to form a twelve point state; And (f) by bit string between adjacent codes among the codes to form a twelve point status and removing the IDLE code that the code is generated; has a. According to the invention, since the transmission bandwidth, reduced compared to the conventional 8B / 10B code can be a long-distance transmission, and is applied with MB810 code without changes for a conventional 8B / 10B coding scheme to the user to select the desired line code It can perform dual-mode operation.
