The ability to deliver any sensor data to any current and future function in the software defined vehicle depends on having the right hardware architecture - one that enables ECU consolidation, centralization of software and provides raw sensor data to the central compute in real time. The asymmetric nature and high bandwidth of video, representing more than 90% of the data in the car, combined with automotive cost pressures, demand dedicated, efficient video transport technology such as OpenGMSL. E2B provides a path to centralized, virtual ECUs for control of sensors and actuators. The paper discusses how these technologies can be combined with an Ethernet core network, and a hardware abstraction layer to create an efficient hardware platform that maximizes the freedom to innovate in software defined vehicles.
