Multi-mode coding and decoding hardware implementation system and method, storage medium and equipment

The invention provides a multi-mode coding and decoding hardware implementation system and method, a storage medium and equipment. The method comprises the steps that a data distribution control module 1 distributes input data 1 to data selectors or mode control modules of different calculation engines according to a data distribution control parameter 1; the mode control module controls XOR operation of the first path of data and the second path of data, or controls the second path of data to pass; the data distribution control module 2 distributes output data of the mode control module to data selectors of different calculation engines according to the data distribution control parameter 2; the check control module controls whether the old check P or Q participates in the calculation, and the calculation is performed by the calculation unit based on the old check and the output data from the data selector. According to the invention, one computing engine is used for realizing three writing modes, and two al
