Abstract
An apparatus comprises a plurality of interfaces, each couplable to a respective one of a plurality of processing circuitries either in a higher criticality compliance state or a lower criticality compliance state. Each interface can receive from its respective processing circuitry interrupt signals destined to a target processing circuitry of the plurality of processing circuitries and transmit to its respective processing circuitry interrupt signals issued by a source processing circuitry of the plurality of processing circuitries. Control circuitry monitors the flow of the interrupt signals and determines whether the flow of interrupt signals exhibits a discrepancy with respect to an expected flow of interrupt signals, and performs a mitigation action in respect of said discrepancy to avoid violation of the higher criticality compliance state.
