Mastering the behavior of multi-core systems to match avionics requirements

Processing Elements use embedded hardware features that worsen Worst Case Execution Time Estimation. Multi-core context implies concurrent accesses that require management to ensure proper spatial and temporal partitioning: Scenario 2 shows that increasing the number of shared resources sometimes increases transaction durations: Scenario 3 and 5 show that unexpected phenomena may appear. First performance results of THALES Avionics´ AMISIS show that the temporal impact of its controls is negligible.
