基于ARM的双操作系统

Two Operation Systems Based on ARM

针对现阶段单操作系统的智能手机和平板电脑等手持设备,提出一种基于ARM的双操作系统.其主操作系统为手持设备本身的嵌入式操作系统,以二进制文件保存,不对开发者开放,通过添加从操作系统和虚拟机,把从操作系统完全开放给开发者.实现了开发者可以通过从操作系统利用手持设备本身的硬件资源,不需要添加任何硬件电路,直接实现对手持设备的二次开发.

Now generally smart phone or Pad is embedded RTOS （ real time operation system） which is based on single core or multi code ARM. They are all based on single OS. This paper brings up one method which the two OS base on ARM core. The main OS is the embedded RTOS which is provided by hand device. And it does not open to developer. By adding the secondary OS and virtual machine, at the same time the secondary OS will fully open to developer. It realizes that the developer can control the hardware source of hand device directly by secondary OS and do not need to add any other hardware. Thus will realize the sec-ondly development for the device without adding any new hardware circuit.
