Bus anomaly detecting methods, processing methods, apparatuses, system, device, and medium

A data processing apparatus, comprising:

• at least one data processing unit configured to send an access request to at least one storage apparatus based on a received task;
• and
• a bus anomaly detecting apparatus, that is configured to:
• at an interface for connecting a bus, activate a detection state in response to at least one access initiating apparatus sending an access request to at least one access receiving apparatus so as to, in the detection state, perform anomaly detection on response signal fed back by the at least one access receiving apparatus for each access request, and block a first interruption signal sent by the at least one access initiating apparatus with respect to a task corresponding to the access request, wherein the first interruption signal is used to inform a processor through the bus that the at least one access initiating apparatus has completed the task corresponding to the access request;
• in response to the response signal corresponding to at least one access request sent by the at least one access initiating apparatus having an anomaly, terminate the detection state, record bus anomaly information based on the response signal having the anomaly, and send a second interruption signal with respect to the response signal having the anomaly, wherein the second interruption signal is used to inform the processor of processing the anomaly of the at least one access initiating apparatus;
• and
• in a case where the response signal corresponding to each access request sent by the at least one access initiating apparatus is received and has no anomaly, terminate the detection state to stop blocking the first interruption signal sent by the at least one access initiating apparatus.
