Problems solved by technology

[0011] After research, the applicant found that for the existing FEC_RS(62,60) code implementation technology, the existing technology does not realize the interleaving function, and does not have the ability to correct the continuous burst error of a certain link
In addition, the ability to judge bit errors in the link is limited, and it does not have the ability to judge and correct multiple bit errors

Abstract

The invention provides an FEC (Forward Error Correction) encoding and decoding module. Some code elements (code words of forward error correction codes) are added in a data code stream of each transmission link through an encoding module, so that the encoding module can accurately judge errors at a receiving end and automatically complete error correction. In order to prevent a certain data link from encountering continuous burst errors in the transmission process, multilink data is interleaved in the design process, and the error correction capability of FEC is utilized to a greater extent, so that the data transmission efficiency and the anti-interference capability of the system are improved.

Description

technical field [0001] The invention relates to the technical field of integrated circuits, in particular to an FEC codec module. Background technique [0002] First, explain the technical terms used in this application: [0003] FEC: (Forward Error Correction) forward error correction. [0004] RS code: Reed-Solomon code. If the RS code is (62, 60, t=1), where t is the number of resistant length characters, corresponding to 60 characters, and the supervisory segment is 2t characters, the coding efficiency of RS(62, 60) is 60 / 62. [0005] PH: The position where the RS codeword is inserted in the link. [0006] Character Block: 240 characters plus 12 PH form a Character Block. [0007] Super Block: 64 Character Blocks form a Super Block. [0008] PM: The start flag of each Super Block. [0009] 1. In the implementation process of the existing FEC_RS (62, 60) code, each link data is independently encoded once by RS Encoder within a unit cycle, and each Character Block (6...
