An FPGA-based Ethernet Audio/Video Bridging (EAVB) network implementation is optimized for carrying high-speed data traffic within the automobile. As 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 new EAVB Development Kit was 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.

The EAVB solution expands the previously released Xilinx Ethernet AVB Endpoint LogiCORE IP into a complete network interface solution, while providing flexibility for addressing a customer’s unique application interface needs. The solution also offers maximum integration potential where Xilinx FPGAs are already commonly used. This includes traditional infotainment connectivity (i.e., host processor companion chip) as well as Driver Assistance (DA) applications, where the FPGA is typically performing image processing for features such as surround view, blind spot detection and real-time lane tracking.

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 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. Further, the system designer can establish any network topology (e.g., star, tree or combination) expanding overall network bandwidth as needed, and up to 75 percent of the bandwidth on any given connection may be reserved to guarantee quality of service for media streaming. The DDC IP cores include 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.

The EAVB Development Kit is based on the Xilinx Automotive (XA) Spartan-6 FPGA, which provides leading system integration capabilities and the lowest total cost for cutting-edge high-volume automotive applications. The DDC/Xilinx EAVB Development Kit is currently available from DDC for $9,999.
