LDPC code translator and implementation method

The invention provides an LDPC code translator and an implementation method. The code translator comprises code translation units, a central control unit and an address generation unit. According to the code translator, the central control unit and the address generation unit are multiplexed through the code translation units which are cascaded, logic sources are effectively saved, and the resource utilization rate is increased; the cascaded structure is adopted for the code translator, and therefore wiring is simple, and work frequency of the code translator is increased; the code translator simultaneously processes multiple codons through a pipeline organization, the number of the code translation units can be reasonably selected according to the practical requirement for the throughput rate of a system, and extremely-high flexibility is achieved.
