Xilinx demonstrated FPGA based Ethernet Audio/Video Bridging (EAVB) network implementation optimized for carrying high-speed data traffic within the automobile. FPGA based Ethernet Audio/Video Bridging (EAVB) network fulfills consumer expectations for higher resolution displays and graphics quality in their driver assistance, navigation and passenger entertainment systems grow, so do the associated challenges of moving content around the vehicle. The demonstration highlights the capabilities of the new EAVB Development Kit co-developed with Xilinx Alliance Program member Digital Design Corp. (DDC) to give automotive system developers the framework and tools necessary to accelerate their development of applications that deliver a richer experience for drivers and passengers.

FPGA-based Ethernet Audio-Video Bridging Network in Car

Xilinx/DDC demonstrated FPGA based Ethernet Audio/Video Bridging (EAVB) Network in Car with video data from four different cameras for 3D vehicle surround view driver assistance, and infotainment

The EAVB demonstration featuring multi-camera driver assistance and infotainment Audio/Video sources streaming, simultaneously on a single network. In addition, a 3D vehicle surround view demonstration built on Spartan-6 FPGAs, showcases Xilinx’s continued commitment to real-time, multi-camera driver assistance solutions.

Ethernet Audio/Video Bridging (EAVB) Development Kit enables developers to build systems based on first-ever fully open network standard optimized for Automotive Audio/Video applications. The IEEE 802.1 EAVB standard is already gaining the attention of a number of leading automotive manufacturers even though the specifications are still being finalized. It is a fully open, flexible and ubiquitous network standard like Ethernet, enhanced to address the unique real-time media streaming needs of automotive systems.

Drivers and passengers are not only expecting higher resolution displays and graphics quality, but critical information needs to be displayed in real-time as drivers are using it to make instantaneous decisions. This development kit proves that EAVB can deliver world-class audio and video quality to passengers while taking advantage of the same Xilinx FPGA devices already on board many driver assistance systems.

The emerging IEEE 802.1 AS, QAT and QAV standards, fully implemented in the Xilinx/DDC EAVB solution, provide for high-fidelity, low-latency audio and video transport in a completely deterministic fashion over a 100Mb/1Gb Ethernet-based local area network (LAN). In the automotive environment, this means a single homogenous LAN can be configured to carry a range of infotainment and DA data content, including system control, audio and video information. Low latency MJPEG video compression is also implemented to further manage network bandwidth.

The DDC IP cores includes facilities for A/V data packetization, media extraction, media clock recovery and stream reservation protocol, as well as handling of legacy Ethernet traffic for generic data or command/control.
