Problems solved by technology

[0009] To sum up, based on the existing auxiliary CPU working state detection scheme, it is difficult for the main CPU to quickly detect the working state of the auxiliary CPU, so it is also unable to quickly perform subsequent reset or switch processing, which also directly leads to network node processing performance Decline

Embodiment Construction

[0035] The technical idea of ​​the present invention is that the auxiliary CPU in the normal working state writes data based on the highly reliable timing interrupt of the hardware, and responds to the hardware writing of the CPU through a dedicated hardware logic unit, so that when the auxiliary CPU breaks down and causes When the data writing is interrupted, the hardware logic unit can respond quickly, thereby replacing the detection method of inter-CPU interaction through inter-board communication in the prior art, and realizing rapid detection of auxiliary CPU faults.

[0036] In order to realize the above technical concept, the present invention provides a method for detecting the working state of an auxiliary CPU, which is suitable for a device with a main CPU and at least one auxiliary CPU, and is used for fast handshaking between two or more CPUs. It should be pointed out that the specific arrangement of multiple CPUs does not affect the realization of the technical sol...

Abstract

The invention discloses a detecting method of an auxiliary CPU operating condition, and a detection system, and also discloses a multi-CPU device and a detection component of the auxiliary CPU operating condition. The detecting method is suitable for an device with a main CPU and at least one auxiliary CPU, and the following steps are executed after the main CPU and each auxiliary CPU is started;based on the hardware interrupt, the auxiliary CPUs periodically perform data writing operation to the second hardware logical cells arranged with the auxiliary CPUs in a one-to-one correspondence manner; when a first hardware logical cell cannot detect that the data of a second hardware logical cell is written after the preset time, the disorder of the corresponding auxiliary CPUs is identified and reported to the main CPU. By the method, the rapid detection of the main CPU to the working conditions of the auxiliary CPUs can be realized, and the high real-time property of the message processing can be further guaranteed; and in addition, the communication band width between the boards is not occupied.

Description

technical field [0001] The invention relates to communication equipment control technology, in particular to a detection method and detection system for the working state of an auxiliary CPU, and also relates to a multi-CPU device and a detection component for the working state of the auxiliary CPU. Background technique [0002] With the continuous increase of processing data and the continuous improvement of people's requirements for processing power, it has become increasingly difficult for devices with only a single CPU to meet actual needs. Therefore, multiple CPUs are often designed on the same device, and external data are sent to each CPU, and each CPU processes related services separately, so as to realize the expansion of the processing capability of the equipment. However, since each CPU is independent of each other, the main CPU is not clear about the state of the auxiliary CPU, so when a certain auxiliary CPU fails, it cannot be taken out of service. [0003] In...
