Thus, it is of great significance to design a gateway for information sharing between different protocols. This work uses hardware software co-design method to implement the concept of the vehicle network gateway. By hardware software co-design, it can compute and modify on real-time. High repetitive tasks which like generator of protocol, use implementation by hardware. Thus the conversion can be greatly increased flexibility, effectively reducing latency on the protocol conversion. The proposed method is design and verification on Xilinx Zynq development platform. To expand the applicability of IVN systems, we proposed a gateway that makes information exchange between CAN bus and FlexRay. Using hardware software co-design approach, the proposed gateway maximum reduces 90% over routing delay and 88.6% over latency.
