| 摘 要： | 分区操作系统是综合化航空电子领域中的核心技术。随着单核性能极限的到来，处理器结构向着多核发展。将两者结合起来，在多核分区操作系统的基础上研究分析多核处理器结构为分区操作系统带来的影响。经分析实验数据得出多核处理器结构在多核处理器中共享Cache结构和内核中临界资源并发访问两方面对分区操作系统产生影响。

| Abstract: | Partition operating system is the key technology of integrated modular avionics(IMA).With the coming of single CPU’s bottleneck,CPU structure is developing toward multi-core.Based on the implementation of multi-core partition operating system,this paper revealed the influence to the partition operating system which is brought by multi-core CPU structure through some well-designed tests.Multi-core CPU structure affect operating system in two aspects,one is the sharing cache of different CPUs;and the other is the kernel lock which protected the concurrent access to critical resources from different partitions on different CPUs. |
