Method for determining fault calculation core in multi-core processor and electronic equipment

Abstract

The invention relates to an electronic equipment fault device detection technology, in particular to a method for determining a fault calculation core in a multi-core processor and electronic equipment. The method is applied to the electronic equipment configured with a multi-core processor, the multi-core processor is integrated with a plurality of computing cores, the computing cores in the computing cores are mutually independent, and the computing cores comprise a first computing core; wherein when the electronic equipment runs, at least one computing core in the plurality of computing cores executes a program instruction, and the program instruction is distributed based on a dynamic scheduling strategy; the method comprises the steps of determining a calculation core corresponding toeach operation exception in N operation exceptions, wherein the operation exception is caused by exception occurring when any calculation core in a plurality of calculation cores executes a program instruction; and when the number of operation exceptions corresponding to the first calculation core in the N operation exceptions is greater than or equal to M, determining that the first calculation core is a fault calculation core and M is a preset value.

Description

technical field [0001] The present application relates to a detection technology for faulty components of electronic equipment, in particular to a method for determining a faulty computing core in a multi-core processor and electronic equipment. Background technique [0002] According to statistics, the probability of abnormal operation such as automatic restart is about 300 / million. If the annual shipment volume is 200 million units, there will be about 60,000 mobile phones with malfunctions such as automatic restarts. [0003] At present, mobile phones have generally adopted a processor integrated with 8 computing cores (core). Although the processor is multi-core, any reliability failure of any one of the multi-cores will cause abnormal operation such as automatic restart of the mobile phone. With the continuous evolution of mobile phone system on chip (SOC) process technology, more and more computing cores are integrated in a processor. Correspondingly, for mobile phon...

Problems solved by technology

This makes it difficult to detect computational core failures

At present, the maintenance outlets of mobile phones are still unable to detect computing nuclear faults, and need to return to the factory for inspection

The return to factory inspection requires the assistance of special tools and repeated pressure tests to do experiments, and manual analysis by professionals can locate the cause of abnormal operation such as automatic restart
