◆ Computing modularly WCET of several applications on a COTS multicore under AMP deployment is an open problem ◎ Gathering WCAT to shared resources is the root problem ◎ This problem was partially closed by removing some constraints ▪ Deterministic home-maid processors ▪ Non modular WCET analysis ◆ We introduced a purely software solution ◎ Configurable resources sharing policy, not visible by guest software ◎ Limited impact on application performances within a usage domain ◆ Future prototype improvements ◎ Main effort on shared resources management capabilities ◎ Deeper experiment with several avionic applications
