RT-Visor:Research on Hybrid Key Systems for Intelligent Wearable Devices
摘要
Abstract
In order to reduce the R&D and production cost of using a combination of low-power chip and performance chip solutions on smart wearable devices,and to reduce the duration of cold reboot switching operating system for single chip solutions,a hybrid critical system RT-Visor based on the embedded virtualization technology is designed and implemented,it supports to realize the hybrid deployment of RTOS and Linux system in the form of software.The hybrid key system uses RT-Thread,a domestic real-time operating system,as the system base,and the virtual machine runs the Linux system.It realizes running RTOS and Linux system at the same time in one chip,the virtual machine can be hung up quickly to realize the fast switching of operating system.Experiments show that RT-Visor can effectively reduce energy consumption when hanging up the virtual machine,and significantly improve the system switching speed compared with the cold reboot switching method,and there is no need for multiple chips to run RTOS and Linux systems separately,resulting in lower R&D and production costs.The performance overhead is less than 3%compared to the Linux virtual machine running on the hybrid key system and the Linux running directly.It provides a low-cost,low-power technology framework for multi-system hybrid deployment.关键词
