针对嵌入式系统安全检测具有独立性、快速性、不干涉应用软件的需求，提出了一种嵌入式系统软件非预期行为检测方法。方法的主要特点是检测系统独立于嵌入式系统，与之并行运行；通过嵌入式系统执行的指令与源程序预期的指令逐条比对，检出嵌入式系统任何不符合源程序的行为；借助哈希运算屏蔽被检系统指令集多样性引入的复杂性，使检测系统对各种指令集的嵌入式系统具有普遍适用性-Have independent safety testing for embedded systems, rapid, non-interference in demand application software, embedded system software presents a unexpected behavior detection method. The main features of the method is that the detection system is independent of the embedded systems running in parallel therewith　performed by the embedded system commands and instructions one by one source than expected, and the detection of embedded systems do not meet the source of any act　With Kazakhstan Xi arithmetic instruction set shield diversity is introduced into the subject system of the complexity of the detection system, a variety of embedded systems with instruction sets of general applicability
