Problems solved by technology

[0004] However, since the interrupt processing process is usually started by an interrupt signal in the prior art, the interrupt processing process is started immediately when the signal is received, and the interrupt processing process is not started if the signal is not received. When the link fails, it will be difficult to receive a signal or receive a wrong signal, and execute the program according to the failure to receive a signal or receive a wrong signal, and it is difficult to find the fault

Embodiment Construction

[0037] Hereinafter, exemplary embodiments according to the present disclosure will be described in detail with reference to the accompanying drawings. Apparently, the described embodiments are only some of the embodiments of the present disclosure, rather than all the embodiments of the present disclosure, and it should be understood that the present disclosure is not limited by the exemplary embodiments described here.

[0038] Application overview

[0039] In a general SOC, an interrupt event will occur in a hardware function module, wherein the hardware function module is such as a network module, an input and output module, a storage module or an image acquisition module, etc. For example, the network module can be an Ethernet module, and the image acquisition module can be a camera etc., and then the hardware function module transmits the interrupt signal to the interrupt controller through the SOC on-chip bus or interrupt signal line. After receiving the interrupt signa...

Abstract

The invention provides a chip fault diagnosis method, which comprises the steps of determining an interrupt flag of an interrupt flag register based on first data for identifying an interrupt state inthe interrupt flag register; and based on the interrupt flag, determining a fault state of chip interrupt corresponding to the interrupt flag. By adopting the technical scheme provided by the invention, the interrupt fault can be diagnosed in time, and the interrupt can be processed in time.

Description

technical field [0001] The present disclosure relates to the field of chip technology, and in particular to a chip fault diagnosis method, device, readable storage medium and electronic equipment. Background technique [0002] It is one of the basic functions of the SOC that the hardware function module in the SOC chip sends an interrupt request to interrupt the software in the CPU. When encountering a predefined interrupt event, the hardware function module sends an interrupt request to the interrupt controller, and the interrupt controller will generate an interrupt signal to the designated CPU to interrupt the routine program of the CPU, so that the interrupt event handler can be prioritized implement. [0003] In a general SOC, an interrupt event occurs in the hardware function module of the SOC, and then the hardware function module transmits the interrupt signal to the interrupt controller through the SOC on-chip bus or interrupt signal line. After receiving the inte...
