We provide software solutions to prevent mutual interference of critical embedded applications when running in a common hardware platform (virtualization). Our hypervisor, XtratuM is space qualified for the ARM Cortex-R5 and A9 and for the rad-hard processor LEON3 of the European Space Agency. XtratuM enables the use of mixed-criticality systems running in the same (multi)core hardware platform. It is a perfect solution for micro and nano satellites and Unmanned Aerial Vehicles requiring to minimize size and weight. XtratuM is complemented by our own LithOS ARINC-653 run-time system and our Xoncrete schedulability analysis tool. Do you want to meet us?
