Reliability of Integrated Modular Avionics Reconfigurable Complexes 000_3.pdf

This paper briefly outlines the problems of calculations reliability for multiprocessor systems. The authors show disadvantages of the statistical calculations method for reconfigurable onboard equipment complexes. The preliminary system safety assessment procedure for the system developed is described. The helicopter onboard equipment complex, which is capable to function in cruise flight mode and in modes of landing and takeoff, was considered as an example. Respective hardware and functional graph was built. The graph takes into account functions criticality, data streams between them, and specific hardware features. Operating modes of the complex are also described. Evaluation of developed reconfiguration algorithms effectiveness was implemented with the use of Fault Tree Analysis (FTA) for the traditional federative architecture with double reservation and for the integrated modular avionics architecture that consists of a crate with the reserved commutation module. Respective fault trees were built and the numerical results of reliability evaluation were presented. In order to improve algorithms for performing better reliability, some recommendations are given. The authors also show the impossibility of implementing the reconfigurable architecture on the basis of the existing complexes with the dynamically reconstructive architecture. The architecture doesn't meet the requirements of complexes reliability and doesn’t comply with modern standards for airborne equipment development.

Task Distribution Algorithm for Multiprocessor Systems of In-tegrated Modular Avionics 35_11.pdf

This paper considers briefly functional tasks distribution problems in multiprocessor sys-tems. It’s shown that the construction of perspective reliable Integrated Modular Avionics System (IMA) is impossible without development of integrated distribution algorithms. The ap-proaches to the functional tasks decomposition problem solving, and a specific character of this problem with regard to integrated complexes of airborne equipment are examined. The functional tasks distribution algorithm among available IMA multiprocessor hardware resources is proposed in order to provide minimum network loading. Helicopter hardware complex is considered as an example. Respective hardware and functional graphs are built and the given tasks are distributed with presented algorithm. This algorithm can be used for IMA crates building and research, and for IMA hardware-to-software interactions mathematical models development.
