Non-Real-Time Hardware-Assisted Computer-System Simulation

The Relative Real-Time Mechanism (RRTM) was designed and developed during Phase I to enable testing of real-time tactical code on development platforms. There are three main areas of planned work for Phase II. The first is the continuation of the RRTM prototype development which will result in a demonstration of its initial capabilities and will allow for experimental trials by government users. The second is the modification of the Kernal-based Virtual Machine (KVM) module to allow for more time control and instruction execution limitation features to be built into KVM. Modifying the KVM module itself will also increase the granularity at which the guest timing mechanisms can be decoupled from the host timing mechanisms. The third main area of work is an investigation into the integration of the RRTM into currently existing userspace virtualization mechanisms. Approved for Public Release | 22-MDA-11215 (27 Jul 22)
