Creating high-throughput publish-subscribe memory backplanes that present physical vehicle signals as standardized data streams across all compute zones.
The Connected Vehicle Systems Alliance (COVESA) Vehicle Signal Specification defines over 2,800 standard data paths (e.g. `Vehicle.Speed`, `Vehicle.Cabin.Door.Row1.Left.IsOpen`). The SDV data fabric embeds VSS trees into kernel lookup tables, eliminating proprietary CAN database (.DBC) reverse-engineering across vehicle models.
When multiple algorithms (e.g. SLAM, object classification, free-space detection) process identical camera streams, duplicating buffers in RAM causes severe memory bus congestion. By implementing POSIX shared memory ring buffers with atomic reference counters, all perception nodes query the same physical memory chunk simultaneously.
