Description

Technical Field

[0001] The utility model belongs to the technical field of embedded systems and relates to a board health management module. Background Art

[0002] With the continuous development of embedded systems, the scale of software and hardware is becoming larger and larger, resulting in increasingly complex system integration and debugging. However, the existing board-level debugging and monitoring methods are not perfect. When a fault occurs, it is difficult to quickly report fault information, such as location, type, cause, etc., and it is difficult to effectively complete emergency processing or fault isolation, resulting in the deterioration of the fault and damage to the product.

[0003] In order to solve this type of problem, it is necessary to add some auxiliary circuits to the basic functions of the product, such as collection, analysis, processing, storage and management circuits. The conventional solution is to integrate these auxiliary circuits with the basic functional circuits on a circuit board, occupying the system's main control chip resources to complete these additional functions. However, this method makes the monitoring channel resources supported by different main control chips vary greatly, resulting in the inability to universalize the auxiliary circuits, and the inability to flexibly transplant the hardware and software development results between different main control chips; and when integrated on a circuit board, the monitoring circuits will be distributed in a messy manner, making it difficult to design according to functional partitions; the external output interface is inconsistent and standardized, and the auxiliary functions and basic functions cannot be modularly designed.

[0004] In summary, the current design of integrating the auxiliary circuit with the basic functional circuit on a circuit board makes the auxiliary circuit non-universal and has poor universality between different hardware boards. Utility Model Content
