This disclosure relates to the field of high-speed serial communication technology, and discloses a method and apparatus for multi-channel data binding and clock compensation based on soft logic. By dynamically configuring a corresponding number of independent buffer units according to the number of transmission channels, and using a recovery clock as the write clock and a unified synchronization clock as the read clock, the output data of each buffer unit is merged into a centralized buffer module. This allows the buffer configuration to automatically match the actual number of access channels, eliminating clock phase deviations between channels and avoiding configuration mismatch problems when the fixed-number buffer scheme expands the channel scale. When a binding code is detected on each transmission channel, the data reading of the corresponding buffer unit is paused and locked at the binding code. Reading is resumed uniformly after all channels have completed locking. This achieves decoupling of multi-channel binding code detection and frame alignment in timing, enabling the soft logic to be compatible with short-interval binding code processing and solving the problems of missed detection and synchronization timeout caused by the fixed processing cycle of native hardware.
