Driver Monitoring Systems (DMS) are safety-critical embedded vision platforms used to monitor driver attentiveness, drowsiness, and distraction. Automotive DMS hardware must support multi-gigabit video transmission, low latency processing, deterministic behaviour, EMI robustness, and compliance with automotive functional safety standards. This paper presents a comprehensive embedded hardware architecture for a DMS consisting of a camera module with FPD-Link or GMSL serializer, an ECU processing unit with deserializer and serializer, and a remote TFT display module. Detailed coverage includes MIPI CSI-2 and DSI protocols, FPD-Link and GMSL selection, connector and cable considerations, Insertion loss budgeting, Power over Coax (PoC) inductor and filter calculations.
