AVnu gears up for car Ethernet profile scuffle

Applications such as ADAS, electric vehicles, high-definition multi-zone A/V and autonomous driving are driving bus performance and AVnu is promoting AVB certification to give automotive manufacturers confidence that all parts of the complex automotive network will work seamlessly together.

"Ethernet and AVB are the natural step for infotainment in the connected automobile to allow for multiple in-vehicle systems to simultaneously access information over a single and high-data-rate network," said Luca DeAmbroggi, principal analyst for automotive semiconductors at IHS Research. "In particular, BMW has demonstrated its strong focus on the deployment of Ethernet technology in the car. With the addition of BMW as a member, the Avnu Alliance is further broadening the number of key players supporting the usage of AVB within the vehicle."

Last month a GENIVI version of AVB from Pelagicore was ported to the R-Car series of automotive infotainment SoC from Renesas. This is directly related to the AVB project started by Pelagicore in the GENIVI consortium in order to produce an automotive Ethernet AVB Reference Software Stack to be made available to all GENIVI members as open source. The Renesas R-Car H2 SoC platform has been chosen because of its AVB support in the MAC, which provides the necessary level of performance and precision for in-vehicle audio and video applications. Pelagicore and Renesas consider this proof of concept as the first step of their cooperation and plan to work together to bring more innovation in the future for in-vehicle infotainment networks.

AVnu member XMOS Semiconductor also has a well-established open source AVB stack running on its automotive qualified deterministic microcontrollers to act as the nodes for an AVB network.
