Mixed-critical real-time systems must meet strict integrity, resilience and timing constraints, as specified by safety standards. Due to the increasing threat of random hardware faults, efficiently achieving high reliability and dependability calls for cross-layer fault-tolerance solutions. This work introduces the Advanced Integrity Q-service (AIQ), a mechanism to ensure the integrity and predictability of on-Chip communication under random hardware faults. Devised for cross-layer and hierarchical fault-tolerance solutions, AIQ realizes low-overhead error detection in hardware and delegates error handling to arbitrary strategies in software. Experimental evaluation featuring benchmark applications and an industrial avionics use case shows that AIQ operates with high reliability and availability and low hardware and performance overheads. In a many-core mixed-critical platform under expected real-time scenarios, AIQ performs with execution time overhead between 1.4% and 7.1%.
