A modeling method of IMA dynamic reconfiguration based on AADL

Abstract

Integrated Modular Avionics (IMA) develops fast and brings more advantages than traditional avionics, such as reducing the hardware redundancy, improving the resource utilization, making the system adaptable and flexible. And the dynamic reconfiguration improves the resource utilization, the flexibility and other advantages as well as the complexity. The safety problems grow as the complexity of IMA increases during the dynamic reconfiguration. AADL is widely used to model a process in the embedded systems. It's especially effective for model-based analysis and specification of complex real-time embedded systems. So we proposed a modeling method of IMA dynamic reconfiguration based on AADL mode, behavioral annex and error model annex in the system level. We also extend the use of the behavioral annex and mode. The model is our first step to analyze and solve the safety problem of IMA system. It can benefit deep analyzing about dynamic reconfiguration of IMA system as the foundation.
