In this paper, it is researched its reliability from the embedded system hardware level. At first, it is defined the goal of the embedded system hardware, and introduced the theory of Markov process. And then, it is set up a single IP hardcore and embedded system hardware Markov model. The last, it is calculated and analyzed the reliability of the embedded controller hardware automatic block in used the established model. Through the results show that the model can be set up in this paper Markov accurate description of the embedded system hardware state change, and can be calculated and analyzed their reliability. Therefore, this research is feasible, the model has certain practical value. 　　 　　The products of embedded system often have hardware failure while in use, which affects the safety and reliability of the system.
