Abstract

The present disclosure provides a chip fault diagnosis method, which includes: determining an interrupt flag of an interrupt flag register based on first data identifying an interrupt state in the interrupt flag register; and determining a fault state of chip interrupt corresponding to the interrupt flag based on the interrupt flag. By adopting the technical solution provided by the present disclosure, a fault of the interrupt can be diagnosed in time, and the interrupt can be processed in time.
