Embodiment 1

[0070] Figure 4 The schematic diagram of the structure of the multi-core system in this embodiment is shown. See Figure 4 In this embodiment, the cores in the multi-core system are divided into: one monitoring core and at least one monitored core. The monitoring core only uses a reset strategy of system reset, while the monitored core can use system reset, single-core reset or related Reset strategies such as nuclear reset.

[0071] The monitoring device of this embodiment includes a system monitoring module, a nuclear monitoring module, a control module, and a storage module. The nuclear monitoring module, control module, and storage module are all located in the monitoring core of the multi-core system. The nuclear monitoring module includes The same number of nuclear monitoring sub-modules, and each nuclear monitoring sub-module is connected to a monitored core. For the monitoring device of this embodiment, the system monitoring module monitors the operating state of the mon...

Embodiment 2

[0094] Figure 6 The schematic diagram of the structure of the multi-core system in this embodiment is shown. See Figure 6 In the multi-core system of this embodiment, the monitoring core and the monitored core are no longer distinguished, and the monitoring of the running status, determining the reset strategy of the abnormal core, and resetting the abnormal core are all completed by the monitoring device.

[0095] The monitoring device here includes a nuclear monitoring module, a control module and a storage module. The nuclear monitoring module also includes nuclear monitoring sub-modules with the same number of cores, and each nuclear monitoring sub-module is connected to a core to monitor the running status of the cores and send the monitoring results to the control module. The control module obtains the monitoring result from the nuclear monitoring module, determines the core in the abnormal state, reads the reset strategy corresponding to the core in the abnormal state fr...

Abstract

A monitoring method of multiple system includes carrying out monitor on all cores being set in multicore system and being on operation state, confirming relevant reset policy for the core when abnormal core is discovered then carrying out reset operation on core requiring to be reset according to confirmed reset policy. The multicore system including core and monitoring unit is also disclosed.

Description

Technical field [0001] The invention relates to monitoring technology, in particular to a monitoring method, a monitoring device and a multi-core system in a multi-core system. Background technique [0002] With the rapid development of computer technology and electronic technology, multi-core technology that integrates multiple chips into one package has gradually matured. Each core in a multi-core system can be regarded as a central processing unit (CPU) in order to improve the processing efficiency of the multi-core system and reduce processing delay. [0003] In a multi-core system, work methods such as pipeline or parallel processing are usually used to complete tasks to be processed. figure 1 Shows a schematic diagram of a multi-core system that adopts a pipelined working mode. See figure 1 , In the pipeline mode, the task to be processed is divided into multiple parts, and each core completes one of the parts. Only after the previous core completes the processing, the la...
