System and method for raising single-board exception handling ability

Abstract

The invention discloses a system and the method to improve the veneer exception handling ability. The system includes the CPU, the reset monitoring circuit and the interrupting trigger module which is connected to the CPU and the reset monitoring circuit to receive the zero clearing signals and transfer it to the reset monitoring circuit. It sends the interrupting signal to the CPU according to the condition and makes the CPU duplicate the data. The system and the method has improved the analysis location capability to the abnormally reset veneer malfunction and the duplicating capability to the operation data. So it can decrease the influence of the veneer abnormally resetting.

Description

technical field [0001] The invention relates to the field of electronics, in particular to a system and method for improving the abnormal processing capability of a single board. Background technique [0002] With the development of communication systems, there are more and more types of network devices, and their functions are more and more complex, and failures will inevitably occur during operation. [0003] The reset monitoring circuit is one of the anti-interference measures of the embedded system. The reset monitoring circuit is divided into a hardware reset monitoring circuit and a software reset monitoring circuit. [0004] In order to make the single board in the device exit the abnormal state after failure and continue to run, the single board is designed with an external dedicated hardware reset monitoring circuit. When the counter in the reset monitoring circuit is full, it will output a The reset signal is sent to the CPU, and the entire board is reset through...

Problems solved by technology

[0014] 1. Every time you switch, you need to perform a stack record, which affects system performance;

[0015] 2. Only the information in the task stack can be recorded, but other information except the task stack before reset cannot be recorded, and the content of the fault record is relatively simple;

[0016] 3. The time of the recorded information may be far away from the reset time, which has no analytical value;

[0017] 4. Business data cannot be backed up;

[0018] 5. Troubleshooting is done passively after the board is reset, which is not timely enough and has a great impact on business

[0024] 1. It is necessary to regularly record task information, which consumes the processing capacity of the system;

[0025] 2. The time of the recorded information may be far away from the reset time, which has no analytical value;

[0026] 3. Only task information is recorded, and business data cannot be backed up;

[0027] 4. Troubleshooting is done passively after the board is reset, which is not timely enough and has a great impact on business
