Embodiment Construction
[0023] In the multi-core CPU communication system, it is divided into one control core and multiple data cores, and the control core and data core share memory.
[0024] Such as figure 1 As shown, the device for detecting data core failures in the multi-core communication system of the present invention includes: a data core monitoring task module, a data core custom task module, and a data core custom task counting module;
[0025] The data core monitoring task module is used to periodically run the data core monitoring task on the control core of the multi-core communication system. When the data core monitoring task is run each time, it detects the number of data core custom task counting modules for the data core custom task. The statistics of the running times. When the data core monitoring task module detects that the counting count of a certain data core custom task counting module is consistent with the counting count detected during the previous run, it is determined ...

The invention relates to a multi-core central processing unit (CPU) management technology and discloses a method for detecting the data core fault in a multi-core communication system. The method solves the problems that in the prior art, the data core fault detection needs to rely on the message receiving and inter-core communication, and the fault detection complexity is enhanced. Custom tasks are in cyclic operation on the data cores, meanwhile, the operation times are counted, monitoring tasks are periodically operated on a control core, the counting state of the operation times of the custom tasks is detected, whether the data core fault occurs or not is judged according to the comparison of former and latter twice detection conditions, the mode does not rely on the message receiving and inter-core communication, the detection method is simple, and the consumed system resources are few. In addition, the invention also discloses a device for detecting the data core fault in the multi-core communication system, and the device is applicable to the communication system with a multi-core CPU.
Description
technical field [0001] The invention relates to multi-core CPU management technology, in particular to a method and device for detecting data core faults in a multi-core communication system. Background technique [0002] In the communication field, with the increasing data traffic, multi-core CPUs have been widely used in various communication devices. There are generally two ways to manage multi-core CPUs: 1. Directly manage multi-core CPUs through the operating system, which cannot maximize the performance of multi-core CPUs; 2. Run the control plane on one of the cores of multi-core CPUs, by The operating system directly manages (this core is called the control core), and runs the data plane on another part of the multi-core CPU (called these cores as the data core). [0003] Since the data core only participates in data processing, the processing process is relatively simple. Therefore, a custom single task is run on the data core, and the single task processes data w...
