An avionics system comprising a central processing unit to implement one or more hard real-time safety-critical applications, the central processing unit comprises a multi-core processor with a plurality of cores, an avionics system software executable by the multi-core processor, a memory, and a common bus though which the multi-core processor can access the memory; the avionics system is characterized in that the avionics system software is designed to cause, when executed, the cores in the multi-core processor to access the memory through the common bus by sharing bus bandwidth according to assigned bus bandwidth shares.
