摘要
在汽车、轨道交通、航空航天等领域,不同安全等级的任务有不同的技术要求,需要在同一硬件平台上运行不同安全关键等级的应用程序,将其称之为混合安全关键系统。分区操作系统具有空间隔离、时间隔离的特性,自然成为了混合安全关键系统的一种选择。随着多核技术的发展,支持多核的分区操作系统也已经逐渐成熟。在混合安全关键的系统中如何确保不同安全等级数据的分发过程成为一个研究重点。将重点研究如何在支持多核处理器的分区实时操作系统中部署以数据为中心的发布订阅中间件,重点分析不同部署方式下需要解决的问题,以及相应的解决方案。
In the fields of automobile,rail transit,aerospace and other fields,tasks with different safety levels have different technical requirements,and applications with different safety critical levels need to be run on the same hardware platform.We call them hybrid safety critical systems.Partitioned operating systems have the characteristics of space isolation and time isolation,which naturally become a choice of hybrid security critical systems.With the development of multi-core technology,the partition operating system supporting multi-core has gradually matured.How to ensure the distribution process of data with different security levels in hybrid security critical systems has become a research focus.This paper will focus on how to deploy data centric publish and subscribe middleware in a partitioned real-time operating system that supports multi-core processors,and focus on analyzing the problems that need to be solved under different deployment modes,as well as the corresponding solutions.
