Abstract: An apparatus for distributing the bus traffic of the multiple camera inputs of an automotive system on chip (SoC) and an automotive SoC using the apparatus are disclosed. The plurality of camera data caches stores data from the plurality of cameras in corresponding internal buffers, measures the data storage status of the buffers, and transmits the data to memory. The bus monitor analyzes a bus signal, and then outputs a signal capable of allowing the plurality of camera data caches to transmit the data via the bus based on the results of the analysis. The master arbiter determines the priorities of use of the bus of the camera data caches, and provides the right to use the bus to the plurality of camera data caches based on the priorities of use of the bus.
