Optionally, the running state of the processor may be checked periodically, a preset difference may exist between the period for checking the running state and the period for updating the diagnostic data, and the preset difference may be such that, each time the diagnostic data updating operation is to be performed, it may be determined whether the running state of the current processor is idle first, if the running state is idle, the diagnostic data updating operation is performed again, and if the running state is not idle, the diagnostic data updating operation is aborted. In order to ensure that each judgment on the running state of the processor is accurate, the preset difference value can be a shorter difference value, for example, the period for checking the running state can be 1 second for updating the diagnostic data in advance.
Optionally, after the local diagnostic data is written in by the first processor or the second processor, a CRC check code corresponding to the local diagnostic data may also be added, so that when the local diagnostic data is read by the second processor or the first processor, CRC check may be performed to verify whether the read local diagnostic data is complete diagnostic data.
