The embodiment of the invention provides a decoding device and method to acquire the decoding group, detects the group to be decoded codeword are all meet the checksum is 0; when the decoding group all codeword checksum is 0 are satisfied, on the implementation of the sign bit decision decoding group. When the decoding group not all code meet the checksum is 0, the detection decoding group in each codeword is performed when the sign bit judgment, the decoding group has at least one execution symbol codeword for each decision, execution symbol judgment code perform data recovery, and each codeword will not perform data recovery after the judgment of the symbol to be decoded codewords into new FEC decoding. When decoding group all codeword checksum is 0 are satisfied, do not perform FEC decoding, perform only the sign bit judgment for each codeword perform multiple decoding process, not every implementation of FEC decoding, reduces the power required for decoding FEC.
