Abstract This paper combines the development status of embedded systems and the characteristics of embedded software for missiles, analyzes the reliability weakness of the missileborne embedded software in order to improve its reliability, and explores the failure modes that may affect the reliability of the missileborne embedded software and classifies them. The development of failure mode and effects analysis (FMEA) is briefly described, and a software and hardware integrated FMEA (S&HFMEA) method for missleborne embedded systems is proposed. Relying on the fivedimensional system of missileborne embedded software reliability guarantee, it uses the S&HFMEA method to analyze the reliability of missileborne embedded software, and explains the principle, implementation process and key points of S&HFMEA. The results show that S&HFMEA has certain effectiveness and practicability for improving the reliability of missileborne embedded software.
