Mastering FAA AC 20-193: Multicore Processor Interference Channel Mitigation

Proving deterministic worst-case execution time when multiple cores share DDR memory buses.

Shared Resource Contention Bottlenecks

When Core 0 executes flight control while Core 1 processes a neural camera stream, simultaneous memory requests to the shared DDR controller cause latency jitter of up to 400%, violating hard real-time safety limits.

Hardware Quality of Service (QoS) Regulators

AirspaceCompute configures hardware memory bus arbiters with strict time-division multiplexing (TDM) and hardware rate limiters, proving mathematically that Core 0 will never experience memory starvation regardless of Core 1 activity.
