Abstract: An electrocardiograph (ECG) signal processing method and apparatus to resolve a problem that relatively severe interference caused during single-arm measurement for single-lead ECG collection seriously affects accuracy of heart rate calculation and cardiac rhythm analysis. The method includes collecting, by a measurement device, an ECG signal, extracting a kth valid QRS complex of the ECG signal, calculating a kth time difference and a (k+1)th time difference, and determining whether the kth time difference and the (k+1)th time difference are target time differences. In this way, accuracy of ECG feature extraction is improved, the interference caused during the single-arm measurement is eliminated to the most extent, and the accuracy of heart rate calculation and cardiac rhythm analysis can be effectively guaranteed.

Abstract: A method includes obtaining a filtered waveform signal, marking the waveform signal as K signal line segments based on monotonicity, extracting line segment data of each signal line segment, and determining a line segment matching template of the waveform signal based on the line segment data of each signal line segment, where the line segment matching template includes M consecutive signal line segments, and M is an integer less than K. The method further includes matching each of the K signal line segments with the M signal line segments included in the line segment matching template, and determining a target wave group of the waveform signal based on a matching result of each signal line segment. The method further includes determining periodic signal data of the waveform signal based on line segment data of the target wave group.

Abstract: A communication chip includes a switching (SW) die and a plurality of network processing (NP) dies. Any one of the plurality of NP dies is configured to: receive a first packet outside the communication chip through an external port, obtain destination information of the first packet, and send a second packet including the first packet and the destination information through an internal port. The destination information indicates a destination NP die of the first packet. The SW die is configured to: receive the second packet, and send the second packet to a first NP die in the plurality of NP dies based on the destination information. The first NP die is configured to: receive the second packet, and send the second packet outward through the external port.
