  • Patent number: 11956134
    Abstract: The disclosure provides a multi-link receiving method and a multi-link receiver. The method includes the following. A reference delay range of a j-th data section is determined according to a preset delay time and a receiving time point of the j-th data section of an i-th data frame. In response to determining that the j-th data section is first received among an N number of data sections of the i-th data frame, the reference delay range of the j-th data section is taken as a designated delay range. In response to determining that receiving time points of the data sections of the i-th data frame are each within the designated delay range, the i-th data frame is restored based on the N number of data sections of the i-th data frame.

  • Patent number: 11609701
    Abstract: The disclosure provides a power management method and a power management device. The method includes: reading a specific memory which includes a plurality of error data records; selecting a specific data record based on a usage status indicator of each error data record; sequentially sending an enable signal to each hardware device; in response to determining that an enable successful response corresponding to the enable signal is not received from a specific hardware device, or a boot alarm is received, at least obtaining a low pin count value and a power management status; recording the low pin count value and the power management status in the specific data record, and accordingly updating the usage status indicator of the specific data record.

  • Patent number: 11575405
    Abstract: The disclosure provides a method for correcting a 1 pulse per second (1PPS) signal and a timing receiver. In the embodiments of the disclosure, the proposed method allows the timing receiver to provide a corrected 1PPS signal with better quality to back-end slave devices, thereby ensuring that the synchronization effect of the slave devices is not overly affected by jitter in a single 1PPS signal.

  • Patent number: 11456810
    Abstract: A synchronization device and a synchronization method for synchronizing a first node and a second node are provided. The first node supports a first time protocol profile, and the second node supports a second time protocol profile. The synchronization method includes: providing a system operating time by a counter; communicating with the first node based on the first time protocol profile to obtain first synchronization information; calculating a time delay according to the first synchronization information, and correcting the system operating time according to the time delay to generate a corrected system operating time; and communicating with the second node based on the second time protocol profile so as to provide the second node with second synchronization information according to the corrected system operating time.

  • Patent number: 11418276
    Abstract: A byte stuffing circuit and a byte stuffing method are provided. The byte stuffing method includes: receiving a first data stream and generating a second data stream according to the first data stream, where a first size of the first data stream is N bytes, and a second size of the second data stream is 2N bytes; in response to an Xth byte of the second data stream matching a first flag byte, overwriting the Xth byte with a first stuffing byte, and inserting a second stuffing byte into an (X+1)th byte of the second data stream, where X is a positive integer between 1 and 2N?1; combining a remnant data stream and a first part of the second data stream to generate a third data stream, and configuring a second part of the second data stream as the remnant data stream; and outputting the third data stream.
