This demo shows an infotainment and ADAS system based on NXP® Ethernet components and is divided in three main parts: Infotainment, Network and ADAS.
In the infotainment part, a “Head Unit” ECU plays locally an MPEG® movie and also streams it over Ethernet to the second “Rear Seat Unit” ECU. Both ECUs also execute in the backroad the NXP AVB SW stack. This enables the two ECUs to be perfectly synchronized with each other. Therefore the two ECUs can playback the very same video (and audio) frame at the same time on their local displays.
In the network part the new Automotive Ethernet Switch (SJA1105EL) and PHYs (TJA1100HN) implement the Ethernet connectivity of the system. The switch executes the AVB “gPTP” synchronization SW that enables the infotainment application described above to operate.
