Abstract: Firstly, a total variation operator is employed to compute second-order delta encoding, which can more effectively utilize the sparsity of EEG signals and significantly improve the compression ratio of EEG signals. Secondly, a fixed dual-buffer module is designed to enable the generation of second-order delta encoded values in a concise and efficient manner. Finally, a serialized bit stream generator is designed to enable second-order delta data collected from multiple parallel channels to be subjected to serialized packaging. It is not only highly scalable, but also suitable for multi-channel acquisition, and can enable reliable interfacing with a subsequent synchronous clock wireless transmission system, thus avoiding the overhead and latency caused by synchronization-asynchronous interface coordination, and further improving the efficiency of signal acquisition.
