Sloth: Threads as Interrupts

Wanja Hofer, Daniel Lohmann, Fabian Scheler, Wolfgang Schröder-Preikschat
2009 2009 30th IEEE Real-Time Systems Symposium  
This approach is not only asymmetrical in its nature, but also introduces problems relevant to real-time systems because lowpriority interrupt handlers can interrupt high-priority threads.  ...  The resulting design of our very light-weight SLOTH system is suitable for the implementation of a wide class of embedded real-time systems, which we describe with the example of the OSEK-OS specification  ...  lower priority than a real-time thread can interrupt and delay the execution of that real-time thread [4] .  ...
