Abstract: A method for updating stored information and an apparatus. A controller performs error correction code (ECC) decoding on stored data information based on the stored data information and stored ECC check information to generate an error-corrected codeword, where the error-corrected codeword includes error-corrected data information. The controller generates candidate to-be-written data information based on the error-corrected data information and a data update indication. The controller performs a mask operation on the candidate to-be-written data information based on the stored data information, and writes unmasked content in the candidate to-be-written data information into a memory.

Abstract: A coding method and apparatus for data communication are provided, and may be applied to a plurality of scenarios such as a metro network, a backbone network, and a data center interconnection. As an example method, a first codeword is formed, where the first codeword includes n image bits and n to-be-transmitted bits. The n image bits are selected from to-be-transmitted bits in m source codewords. The m source codewords are formed before the first codeword. Both n and m are positive integers, and n>m; The n to-be-transmitted bits in the first codeword are sent. The bit in the first codeword can be protected by a plurality of codewords generated at different moments. In addition, the bit in the codeword can be protected by different quantities of codewords.

Abstract: This application provides a data processing method and a second communication apparatus, to resolve a problem of relatively long data synchronization time in a conventional technology, and may be applied to augmented reality AR, virtual reality VR, artificial intelligence AI, cloud applications, or other fields. The data processing method includes: A second optical module receives first data from a first optical module, and determines out-of-synchronization lock based on the first data. The second optical module sends, to a second host, first indication information indicating that the second optical module is in out-of-synchronization lock state. The second optical module receives second data from the first optical module, determines synchronization lock based on the second data, and sends, to the second host, second indication information indicating that the second optical module is in synchronization lock state.
