汽车网络中多核SoC的NoC结构研究

Study on the Architecture in NoC of SoC with Multi-CPU in Automobile Network

将汽车电子信息网络划分为通信信息系统和测控系统两个部分,设计了汽车通信信息系统和发动机控制系统两个不同的SoC结构。这两个SoC都属于多CPU的SoC,其中数据传输结构比较复杂。在对汽车电子网络分析的基础上,对汽车通信信息系统SoC和发动机控制系统SoC的结构进行了研究,设计了两种网络的SoC结构。作为一种特殊的片上网络结构,根据所提出的SoC结构,提出使用关联矩阵分析SoC中连接条件的NoC设计分析方法。

Automobile electronic information network is divided into two parts, communication intormation system and measure and control system. And two different SoC architectures are designed in this paper. Based on the analysis of automobile electronic network, the architecture of communication information system SoC and engine control system SoC are analyzed in the paper, and the architecture of SoC in two networks is designed, too. Based on the architecture of the SoC, a NoC design and analysis method of affiliated matrix is proposed in the paper to analyse connection conditions in SoC.
