A Design of a Communication Processor for Implementing Local Network in Zonal Architecture

As the complexity of in-vehicle network is increased, zonal architecture is proposed for the next generation network architecture. The zonal architecture divides the in-vehicle network into local networks and interconnects the local networks in a central gateway. This paper proposes a local network processor based on local interconnect network (LIN). The processor includes a light-weight core and dedicated LIN controller to achieve design goals such as design area and performance. The processor is fabricated with TSMC 180nm CMOS process and the characteristics are compared to Samsung 28nm process.
