Embodiment Construction

[0030] Step 41, setting a memory track field for each memory block in the multi-core system.

[0031] In the embodiment of the present invention, first, the dynamic memory area of ​​the multi-core system is divided into blocks, and an independent management unit is configured for each memory block in the dynamic memory area, and the management unit corresponds to the memory block one by one.

[0032] Set the memory track field and the application program for recording the memory track in the above-mentioned management unit, the application program is used to record the number information of the CPU that the memory block passes through during the transfer process, and save the recorded number information of the CPU in the memory track field middle. The application can be embedded in a memory receive or send processing application. The size of the memory track field is determined according to the number of CPUs that need to pass through during the transfer of the memory block. ...

Abstract

The present invention provides a method and apparatus for detecting memory transferring abnormity in a multi-core system, the method comprises: recording a transferring track condition of the memory in the multi-core system; detecting the abnormal condition of the memory in transferring according to the track condition. The apparatus mainly comprises a transferring track recording module for recording transferring track condition of the memory in the multi-core system; a memory transferring abnormity detecting module for detecting the abnormal condition of the memory in transferring accordingto the track condition recorded in the transferring track recording module. According to the invention, the problems that the process for detecting the memory transferring abnormity is complicated, the detecting efficiency is low and the existing method is not suitable for detecting the memory transferring abnormity condition of combined path can be solved.

Description

technical field [0001] The invention relates to the field of computer applications, in particular to a device and method for detecting memory transfer exceptions in a multi-core system. Background technique [0002] In today's electronics, communications, and IT industries, the testability and maintainability of the operating system are indispensable, and more and more attention has been paid to it. Among them, the memory exception location technology of the operating system is a key technology. In a multi-core system, multi-cores need to communicate freely and communicate with the outside world. Memory abnormalities are more complicated. If the cause and transmission link of memory abnormalities can be recorded in the first time, the efficiency of abnormal location can be improved, and then the customer satisfaction. [0003] A memory anomaly detection method in a multi-core system in the prior art is: using a segment search method (ie, segment exclusion) method to detect ...
