Abstract

The increasing number of driver assistance, infotainment and entertainment systems in automobiles results in higher requirements for bandwidth, fault tolerance and timing behaviour concerning the in-vehicle communication structure. In future, in-vehicle networks based on current technologies will reach their limits due to insufficient scalability and complexity. Real-time (RT) Ethernet is a new, scalable approach to reduce the complexity of these networks significantly. This paper demonstrates the architecture of a RT Ethernet prototype platform based on an ARM centred system-on-chip, which achieves timing and bandwidth characteristics of a typical future automotive application. It is based on an advanced interrupt driven architecture.
用于汽车应用的实时以太网原型平台
随着汽车中驾驶辅助、信息娱乐和娱乐系统的不断增加,对车载通信结构的带宽、容错性和定时行为提出了更高的要求。未来,基于现有技术的车载网络将因扩展性和复杂性不足而达到极限。实时(RT)以太网是一种新的、可扩展的方法,可以显著降低这些网络的复杂性。本文展示了基于ARM为中心的片上系统的RT以太网原型平台的架构,该平台实现了典型的未来汽车应用的时序和带宽特性。它是基于一个先进的中断驱动架构。
