摘要:
针对现存的基于软件的虚拟化解决方案存在的不足,利用ARM标准硬件技术和赛灵思ZC702商业平台,实现通用操作系统(GPOS)与轻量级实时操作系统(FreeRTOS)同时运行.测试结果表明:虚拟机从RTOS到GPOS的上下文切换系统开销是3.10 μs,相反过程为2.64 μs,内存占用也仅为1 KB;由虚拟机监视系统(VMM)引入的性能开销低和内存占用较小;利用ARM TrustZone技术可实现一个具有低成本和高可靠性的轻量级虚拟化解决方案.
Abstract:
According to the existing solution scheme of software based virtualization, the arm standard hardware technology, combined with the mature technology of Xilinx ZC702 business platform, the general-purpose operating system(GPOS)and real-time operating system(FreeRTOS)system running at the same time are realized. Test data shows that the virtual machine from the RTOS to GPOS system context switching overhead is 3.10 μs, opposite is 2.64 μs, memory is only 1 KB; the performance overhead introduced by the virtual machine monitor(VMM)is low and with a smaller memory footprint; ARM TrustZone technology is exploited to implement a lightweight virtualization solution with low overhead and high determinism.
