Abstract

The invention relates to a protection and diagnosis method for an embedded multi-core processor, which is characterized by comprising the following steps of: 1, distributing an application program memory space for each core of the embedded multi-core processor and setting a space attribute; step 2, implanting a check code probe and a running probe into the memory space with the spatial attribute of the code segment, and implanting the running probe into the application program so as to check the application program based on the probes; and step 3, based on the verification result, executing a guarding task to process the application program. The method disclosed by the invention is simple, occupies few resources, and can accurately acquire the application program running condition of each core in the multi-core processor in real time and determine whether the application program code and the data content are accurate or not.

Description

technical field [0001] The invention relates to the field of data processing, and more specifically, to a method and device for protection and diagnosis of an embedded multi-core processor. Background technique [0002] At present, in embedded control equipment, with the updating and upgrading of embedded chip technology, the use of multi-core processors is becoming more and more common, the functions of equipment are becoming more and more complex, and the performance requirements are getting higher and higher. Therefore, a large number of multi-threaded application architectures have been used in embedded devices. [0003] Concomitantly, various problems have also appeared in multi-core processors, for example, the risk of device software failure due to various reasons, abnormal memory reversal due to hardware failure, and data content error writing due to software defects, etc. . In industries with high reliability and safety requirements, accidents caused by equipment ...
