3 Camera Connection

Generally, side view cameras and surround view cameras are connected and processed on two TDA4x SoCs . However, the front camera typically needs to implement more L2, L2+ functions such as Object Detection, Semantic Segmentation, Lane Keeping/Changing Assist and so on. When the computing power of one TDA4x SoC cannot support such multi-functional implementation, then front camera input needs to be routed to the second TDA4x SoCs for additional processing. This section introduces two methods to connect front camera to TDA4x SoCs.
