Design of application layer software and interface circuit for the MOST network in vehicle

In this paper, the structure and protocol of MOST (Media Oriented Systems Transport, MOST) network are described. And then, the corresponding relationship between MOST network layer and hardware layer is analyzed. For designing electronic control unit with the MOST network interface, the MOST network interface circuit is discussed. By analyzing the accuracy of the device parameters of interface circuit and experimental results, the design requirements of the device parameters are presented. The experimental result shows that the design method is feasible and the transmission of MOST network information can be realized.
