基于汽车全液晶式仪表屏蔽处理器和单片机通信协议差异性的研究
首发时间:2017-06-20
摘要:汽车驾驶舱的全液晶式仪表以其传统仪表无法比拟的优势,得到越来越快速的发展。全液晶式仪表一般采用两块芯片:单片机和通用处理器。这两块芯片进行消息的交互,要依赖于总线的通信协议,但通信协议随着不同的公司或不同的项目,往往会发生变化,这就导致了解析这些消息的应用层程序会随着消息协议的变化而要做繁琐复杂的更改,增加了软件移植的复杂度。本文提出了一种特定的中间层消息框架,用于屏蔽处理器和单片机的通信协议差异性,减小软件移植的复杂性。

Research on shielding the difference of communication protocol between processor and MCU based on full size cluster
Abstract:Full size cluster in automotive cockpit develops rapidly with its incomparable advantages in traditional instrument. The cluster uses two main chips: MCU and general processor. Interacting with messages between two chips depends on the communication protocol. However, the protocol is changed with different companies or different projects. After that, the application program which needs to parse the protocol will be changed complexly and tediously. This paper proposes a software message framework to shield the difference of protocol between MCU and general processor and to reduce the complexity of software porting.
Keywords: Message Framework Full size cluster Communication protocol
