XtratuM

XtratuM is a software which allows different applications to share the same hardware without interference.

XtratuM hypervisor is a software which enables critical and non-critical applications to share a common hardware platform without interfering with one another in terms of error propagations, for example.

XtratuM hypervisor is an embedded software which provides virtualization, allowing different applications with different criticality levels to share the same hardware platform through the isolation in time and space of their execution environments.

XtratuM is an embedded space-qualified type 1 hypervisor that provides virtualization, allowing that different applications share the same hardware platform through the isolation in time and space of their execution environments, also called partitions. Through the use of XtratuM, developers can build bare-metal applications or use different operating systems over the same platform, as well as to allocate applications with different criticality levels to each partition, ensuring that if a partition fails, the others continue working.

XtratuM is an embedded ECSS category B qualified type 1 hypervisor aimed at safe and efficient embedded real-time systems through virtualization, allowing different applications to share the same hardware platform through the isolation in time and space of these applications in partitions (TSP). Thanks to XtratuM, developers can build bare-metal applications or use different operating systems over the same platform, as well as to allocate applications with different criticality levels to each partition. The use of XtratuM is convenient for systems in which the main challenges deal with safety, the reuse of certified applications, dynamic software updates and size, weight, power and cost reduction of embedded safety-critical systems.
