| Abstract: |
System reconfiguration at run time is extensively used in general purpose applications. In the field of embedded real-time systems, the applicability of these techniques is limited by the
specific requirements of such systems, mainly the need of sustaining a well-balanced work load under all circumstances while maintaining deterministic behavior. In cases where reconfiguration is
inevitable because the use of available resources must be optimized, it is commonly accomplished either through the underlying operating system, or directly from within a programming language.
The shortcomings of these approaches, such as a need for dynamic scheduling mechanisms or the impact of language implementations on different platforms, can be avoided when only data is swapped
in and out, and the code itself remains unaltered. Generated applications with these features permit the realization of systems with the postulated dynamic properties while retaining all the
advantages of a static solution. |
