    • Methods and systems to broadcast sensor outputs in an automotive environment allow sensors such as cameras (108) to output relatively unprocessed (raw) data to two or more different processing circuits (406, 412) where the processing circuits are located in separate and distinct embedded control units (ECUs). A first one of the two or more different processing circuits processes the raw data for human consumption. A second one of the two or more different processing circuits processes the raw data for machine utilization such as for autonomous driving functions. Such an arrangement allows for greater flexibility in utilization of the data from the sensors without imposing undue latency in the processing stream and without compromising key performance indices for human use and machine use. Each camera 108(1)-108(M) of camera system (400) is associated with an embedded control unit (ECU) (402(1)-402(M)), each ECU including a serializer/deserializer (404(1)-404(M)). Cameras (108(1)) and (108(2)), have no operator function and thus send their output to a computer vision ECU (406) and, in particular, to a deserializer/ serializer (408) therein for processing by a computer vision system on a chip (SoC) (410). Cameras (108(3)-108(M)) are useful for both operator assistance as well as autonomous driver assistance system, ADAS, functions. Serializers/deserializers (404(3)-404(M)) include dual-port outputs that provide raw image data not only to the computer vision ECU (406), but also to an infotainment ECU (412). The computer vision ECU (406) is separate and distinct from the infotainment ECU (412). A deserializer/serializer (414) receives and deserializes the data before passing the data to an infotainment SoC (416) having an associated display (418). This arrangement allows for relatively low latency as the data is not processed by one circuit and then passed to the other circuit for further processing.
