RTOS vendors may provide partitioning mechanisms for their multicore processors, but these do not guarantee the complete elimination of multicore interference. Instead, they are designed to provide an upper limit on interference, sometimes at the expense of average-case performance.
In aerospace, these partitioning mechanisms may be referred to as ‘robust partitioning’. The multicore guidance in AC 20-193, AMC 20-193 and CAST-32A identify allowances for some of the objectives if you have robust partitioning in place, but it is still necessary to verify that the partitioning is as robust as it is claimed to be.
From a certification standpoint, regardless of the methodology behind the RTOS vendor’s approach to eliminating interference, the effectiveness of the technology needs to be verified.
