The VCU project of a research institute of China Railway leads the new trend of localization of the operating system
business pain point
1) The underlying core technology of the train control system is monopolized by foreign capital, and it is easy to be "stuck"
2) Business units of different security levels are integrated into one domain controller, and it is difficult to achieve business isolation and non-interference between systems of different security levels
solution
Intewell-HyperI is applied to the nationally produced VCU (train control unit) based on Godson, using virtualization technology to implement multiple completely isolated virtual machines on one CPU, and each virtual machine can run different applications separately; the virtual machine provides time Table and priority hybrid scheduling capability ensures the deterministic and real-time running time of virtual machines.
value of customer
1) The core has passed IEC61508SIL4, helping customers pass safety certification efficiently and speeding up product launch
2) Hypervisor adopts micro-kernel technology, which is deterministic and reliable, ensuring reliable operation of vehicles
3) Support partition isolation and provide a highly safe and reliable operating platform for rail transit application software
4) After the strict source code autonomy rate scanning by the Fifth Institute of Electronics of the Ministry of Industry and Information Technology, the source code autonomy rate of the kernel and some key modules has reached 100%
