基于HMP架构CPU的民机多安全级别系统实现方法

HMP CPU-Based Multi-Security Level Software Implementation Solution

提出了一种基于HMP异构多核CPU和资源域控制器的设计方案,可部署在同一物理CPU上并满足DO178C标准的多安全级别软件运行要求。首先讨论了HMP异构多核CPU和资源域控制器的相关概念及作用,接着介绍了多安全级别系统的实现方案,最后在NXP iMX6系统平台上进行设计和实现。结果表明,该方案可成功地实现在机载设备上将不同安全级别的软件部署在同一物理CPU上的需求,方案具有灵活、成本低廉和功能可靠的优点。

A design scheme based on HMP heterogeneous multi-core CPU and resource domain controller is proposed,which can be deployed on the same physical CPU and meets the multi-security level software operation requirements of the DO178C standard.First,the related concepts and roles of HMP heterogeneous multi-core CPU and resource domain controller are discussed,then the implementation of multi-security software is introduced,and finally designs and implementation are carried out on the NXP iMX6 system platform.The results show that the solution can successfully implement the requirements of deploying software of different security levels on the same physical CPU on the airborne equipment.The solution has the advantages of flexibility,low cost and reliable functions.
