Dynamic software updates for real-time systems
Proceedings of the 2nd International Workshop on Hot Topics in Software Upgrades, 2009•dl.acm.org
Seamlessly updating software in running systems has recently gained momentum.
Dynamically updating the software of real-time embedded systems, however, still poses
numerous challenges: such systems must meet hard deadlines, cope with limited resources,
and adhere to high safety standards. This paper presents a solution for updating component-
based cyclic embedded systems without violating real-time constraints. In particular, it
investigates how to identify points in time at which updates can be performed and how to …

Seamlessly updating software in running systems has recently gained momentum. Dynamically updating the software of real-time embedded systems, however, still poses numerous challenges: such systems must meet hard deadlines, cope with limited resources, and adhere to high safety standards.
This paper presents a solution for updating component-based cyclic embedded systems without violating real-time constraints. In particular, it investigates how to identify points in time at which updates can be performed and how to transfer the state of a component to a new version of the same component. We also present experimental results to validate the proposed solution.
