Problems solved by technology

[0004] However, the existing single-module structure cannot support multi-standard RS codec implementation, and additional external control logic needs to be added
Moreover, since the RS codecs of different specifications are implemented using a combination of independent modules, the internal storage resources and computing resources of the modules cannot be reused, resulting in additional waste of resources

Abstract

The invention relates to a multi-specification Reed-Solomon (RS) encoding and decoding method, a device and a system. By arranging a register, a multiplier, a syndrome generating unit and other functional modules needed by realizing encoding and decoding of maximum check code element RS codes, and according to the RS code check code element specification adopted in the processes of encoding and decoding, the functional devices of the corresponding number are controlled and started, thereby realizing the encoding or decoding process of multi-specification RS codes in a hardware structure, and greatly improving the resource utilization rate in the process of realizing encoding of the multi-specification RS codes.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a multi-standard Reed-Solomon RS coding and decoding method, device and system. Background technique [0002] Reed-Solomon (RS: Reed-Solomon) codes are a class of linear error-correcting codes with good performance. It can correct both random errors and burst errors, and has strong error correction ability, especially in short and medium code lengths. It is widely used in fault systems, especially in digital communication and storage systems. [0003] The solution in the prior art, for a system that needs to support different transmission and reception rates, usually adopts the method of setting up multiple RS codec modules, or separately designing RS codecs of different specifications, and then combining them together, and adding The standard control logic selects the input and output of each codec, so as to realize multi-standard codec. [0004] However, the existing ...
