Research on Multi-Kernel Fusion Technology for Highly Reliable Embedded Operating Systems

In a multi-core environment, multiple cores need to share some hardware resources, which can lead to data inconsistency or competition conditions, making multi-core fusion very difficult. A highly reliable multi-core fusion technology for embedded operating systems has been designed. Establish integrity measurement rules for multi-core operating systems, and evaluate the integrity of multi-core fusion based on the transmission rules of measurement capabilities and trust transmission rules to ensure the security of multi-core fusion. Adapt high reliability embedded operating system multi-core fusion stack from the aspects of microkernel layer, inter process communication layer, shared memory layer, message queue layer, real-time scheduling layer, fault-tolerant protocol layer, network communication protocol layer, security protocol layer, HAL layer, power management layer, etc. Considering the dependencies and sharing between tasks, the parallel fusion of multi-core threads in embedded operating systems uses synchronous fusion and parallel scheduling mechanisms to avoid data competition and deadlock problems. Through comparative experiments, it has been verified that this technology has higher throughput, higher fusion efficiency, and significant advantages in application performance.
