Abnormality processing method and device for system component

The invention discloses an exception handling method and device for a system component, the method is suitable for a computing core which performs external bus connection or internal bus connection with different system components, and the method comprises the following steps: when the working state of the system component is detected to be abnormal in real time, obtaining a component processing request, the component processing request is a processing request independently sent by a component with an abnormal working state; and in response to the processing request, a processing command is sent to the component in the abnormal working state, so that the component in the abnormal working state independently carries out exception processing operation, and the exception processing operation comprises restart or recovery. According to the method, the working state of each component connected with the computing core can be detected, and the restart or recovery instruction is sent to the abnormal component when th
