Look Mum, no VM Exits! (Almost) [article]

Ralf Ramsauer, Jan Kiszka, Daniel Lohmann, Wolfgang Mauerer
2017 arXiv   pre-print
Multi-core CPUs are a standard component in many modern embedded systems.  ...  This retains, with negligible system overhead, Linux's feature-richness in uncritical parts, while frugal safety and real-time critical workloads execute in isolated, safe domains.  ...  Unlike other real-time partitioning approaches (e.g., PikeOS [10] ) that aim to manage hardware resources and may forbid direct access by guest systems, Jailhouse only supports direct hardware access.  ...

Automated generation of explicit connectors for component based hardware/software interaction in embedded real-time systems

Wolfgang Forster, Christof Kutschera, Andreas Steininger, Karl M. Goschka
2008 Proceedings, International Parallel and Distributed Processing Symposium (IPDPS)  
The complexity of today's embedded real-time systems is continuously growing with high demands on dependability, resource-efficiency, and reusability.  ...  Second, components can be shifted from software to reconfigurable hardware, typically field programmable gate arrays (FPGAs), in order to meet real-time constraints.  ...  We would especially like to thank Martin Zauner from the University of Applied Sciences Technikum Vienna for supporting us in getting experiences with the ESTEREL design flow.  ...
