Abstract

Temporal partitioning schemes for FC OFP of T-50/FA-50. Fault Handling: Task-level & Partition-level; Task-level fault-tolerance scheme: each partition handles its task fault; Partition-level scheme recovers a task fault by re-executing the faulty partition. The schedulability analysis of both schemes based on the temporal partitioning of FC OFP: the proposed schemes meet the real-time requirement of FC OFP with consideration of faults. Our on-going work includes: More analysis of fault-tolerance schemes in HRTSF; Implementation of the framework; Experimental evaluation in the test platform; Provide a new FT-HRTSF based on the T-50/FA-50 avionics systems.
