Research of automotive network FlexRay/CAN gateway based on DSP

In order to achieve data communications between FlexRay and CAN vehicle networking bus with different protocol and different rates, a simple FlexRay/CAN gateway was designed in this paper. DSP was a core processor and connected with FlexRay and CAN network nodes to achieve the network physical layer. Protocol software was designed on the basis of analysis of the two protocols and Network protocol conversion was implemented. Resource is shared on the FlexRay bus and CAN bus through the bridging of gateway.
