Design of on-vehicle radio node based on OS81050 in MOST network

The design process of on-vehicle radio node is described in this paper which supports connections to MOST network and takes use of MOST intelligent network interface controller chip. The design process includes system design, hardware architecture and software architecture, and is verified feasible by real experiment. The innovations of the work described in this article are the use of a new generation of intelligent network interface controller and the combination with traditional on-vehicle radio and the MOST network to realize audio signals, control signals and feedback information transmission through the optical fiber simultaneously, which reduces the development process.
