Paper Abstract:
|
The paper presents a new method for re-configuration of tasks or a process in an embedded avionics application. The
proposed algorithm works based on four control parameters: re-configurability Information factor, Schedulability
Test/TL/UF, Context Adaptability/suitability and Context Flight Safety. The algorithm is data centric and interfaces
system health as control input and initiation of the re-configuration is only after successful evaluation of the parameter
metrics. It enhances the availability and reliability of the system under failed conditions by efficient selection and
procedural re-configuration with safe state exit. The advantage of the new approach over the non-configurable systems is
the increased availability of flight critical applications under failed conditions. It also preserves the advantages of non-
Reconfigurable systems over federated architecture. Invalid failure of control parameter brings the system to safe state.
The scheme, algorithm and the control parameters metrics and their validation approach are described. The algorithm is
novel in terms of dynamic re-configuration compared to existing static avionics architecture |
