摘要
在机弹载设备综合化、智能化、低功耗的发展趋势下,嵌入式系统设计中近几年也广泛采用了ARM系列处理器。其中ARMv7的VMSA(虚拟存储系统架构)支持虚拟化扩展、安全扩展以及大物理地址扩展,使得多虚拟机的运行或分区操作系统实现有了硬件系统的支持,复杂嵌入式设备可采用新一代嵌入式处理器完成系统综合化与小型化。主要针对ARMv7-A体系结构中扩展后的VMSA内存管理的应用结构变化进行了研究,并就其在机载设备上的应用方式进行分析,为ARM处理器在机载设备的应用提供了技术支撑。
As the development trend of integrated, intelligent and low power application in embedded systems, ARM series proces-sors have been widely used in recent years. Virtualization extensions, security extensions, and large physical address extensions sup-ported in ARMv7 ′ s Virtual Memory System Architecture（ VMSA）, This allows for hardware system support for the operation of multiple virtual machines or the implementation of partitioned operating systems. Complex embedded devices can use the new generation of embedded processors to complete system integration and miniaturization. This article focuses on the changes in the application struc-ture of the memory management of extened VMSA in the ARMv7-A architecture. And also analyzed the application on airborne e-quipment. This will provides technical support for ARM processor used in airborne equipment applications.
