FLEXRAY COMMUNICATION CONTROLLER FOR FPGA- BASED AUTOMOTIVE SYSTEMS AS AN IP CORE
Satya Shree, Sai Ram · 2015
Time-triggered protocols like FlexRay have been gaining ground as the standard for high-speed reliable communication in the automotive industry, marking a shift away from the event-triggered medium access used in Controller Area Networks (CAN). This paper describes an FPGA-based communication controller which features configurable extensions to provide functionality that is unavailable with standard implementations. It is implemented and verified on a Xilinx Spartan 6 FPGA, integrated with both a logic-based hardware ECU and a fully-fledged processor-based ECU. We demonstrate that the flexible extensions help enable advanced applications that integrate features like fault-tolerance, timeliness and security.
