The Controller area network completely addressed the requirements of the automotive networking until the last decade. However with advancement in the automotive electronics puts requirement of a deterministic and fault tolerant communication systems. Flexray was introduced to address this issue. But Flexray is costly compared to the CAN. Flexray is not seen as the complete replacement for CAN. The current automotives use a mix of communication protocols. There is an occasional need for data exchange between these two protocols for which gateways are required. But gateways are costly. Communication controllers are the core of the data link layer and required for a connection to these networks. In gateway implementations, usually a host that is connected to the two networks does the data conversion in application . Here, a model is proposed at system level for integrating these controllers for achieving host independent interprotocol communication, without the use of gateways and no intervention from the application. An open core IP for CAN CC is used as reference, and for Flexray CC, a simple model, mostly serving as a black box is built taking NXP’s MFR4310 as reference.
