针对异常发生时无法及时有效利用异常发生的上下文信息的问题，在堆栈回溯获得上下文信息的基础上，提出一种能够记录异常信息便于线下分析，同时能够基于预设规则库支持线上对系统应用进行重构的异常处理方法。对PowerPC构架下的堆栈结构进行研究并设计基于堆栈回溯的函数溯源算法；对系统工作状态进行分析抽象，采用有限状态机建立系统异常处理时的状态迁移模型，阐述异常处理的设计实现过程。实验结果表明，该方法能够有效实现对异常的线上线下处理，提升了改进系统应用缺陷的效率，增强了系统应用的容错性和健壮性。

To timely and effectively use the exception context ,an exception handling measurement based on the stack traced in‐formation was proposed .When the exception occurred ,the exception information in favor to resolve the defects of the application was logged after the experiment ,and the event was dealt with according to the configuration of the system .After the stack structure of the PowerPC architecture was studied ,a stack trace algorithm was designed .Based on the abstraction of system working state ,the FSM was adopted to model the system working transition of exception handling .On the basis of these opera‐tions ,an implementation of exception handling was introduced .The experimental results show that this measurement can handle the exception event effectively when it occurs or when the device not runs after it occurs .And the measurement improves the fault tolerance and robustness of the system ,as well as the efficiency of improving application defects .
