摘要
针对嵌入式操作系统VxWorks下的异常机制在平台之间可移植性差的问题,提出了一种与具体处理器类型无关的异常处理方法,此方法增强了软件异常处理的可移植性和健壮性。最后,结合x86处理器,详细阐述了该异常处理方法的原理以及现场分析、异常恢复策略的具体实现方法。
According to the VxWorks RTOS＇s poor portability between the Terraces,this paper presented a new method of exception handling which is unconnected with the Processors＇ type,the transplant and haleness of exception handling had been strength.At last,the implementation of exception handling had been illustrated with a kind of x86 processor.
