  • Patent number: 9891978
    Abstract: A system and method may ensure certified operation of a safety-critical avionics system incorporating a multi-core processor (MCP) aboard an aircraft via external architectural mitigation. A redundant processing element (RPE) may be associated with a processing core of the MCP and with safety-critical applications configured to execute on the core. The critical applications generate critical results based on sensed critical data parameters and pass the parameters and results to an external system monitor. The system monitor performs fault detection external to the original core by comparing the critical results and the critical data parameters and notifies the associated critical application if a fault is detected. The associated critical application may then log the fault to a fault history, reset an associated sensor, or notify the crew of the fault.
