摘　　要：嵌入式系统产品在使用过程中经常出现硬件故障,从而影响系统的安全可靠性。从嵌入式系统硬件层面研究其可靠性。首先定义嵌入式系统硬件目标,简单介绍了Markov过程理论;建立了单个IP硬核和嵌入式系统硬件的Markov模型;应用所建立的模型,对嵌入式站间自动闭塞控制器硬件进行了可靠度计算和分析。实验结果表明,该Markov模型能够准确描述嵌入式系统硬件的状态变迁,并能计算和分析其可靠度,具有一定的实用价值。The products of embedded system often have hardware failure while in use,which affects the safety and reliability of the system.In this paper,its reliability was researched from the embedded system hardware level.At first,it defined the goal of the embedded system hardware,and introduced the theory of Markov process.And then,a single IP hardcore and embedded system hardware Markov model was set up.At last,the reliability of the embedded controller hardware automatic block was calculated and analyzed through the established model.The results show that the Markov model can accurately describe the embedded system hardware state change,and can calculate and analyze their reliability.Therefore,the model has certain practical value.
