摘　　要：针对嵌入式操作系统软件开发过程中的缓冲区溢出现象,提出一种基于边界检测的缓冲区溢出检测方法,给出该方法的理论基础,描述实验步骤及实验过程,该方法为需检测的数据缓冲区与检测变量分配连续的内存区域,通过检测变量的改变与否直观的检测出缓冲区是否溢出,并执行相应的告警和补救措施。In the phenomenon of buffer overlfow of operating system for embedded software development process,a buffer overlfow detection method is proposed which is based on boundary detection.The theoretical basis of this method is given and the experimental procedure is described.This method al ocate contiguous memory area for data buffer and detection variables that require testing and it can intuitive detect whether the buffer overlfow by detecting changes in the variables,and then execute the corresponding alarms and remedies.
