English abstract:
The increasing complexity of speed-up mechanisms found in
modern computer architectures makes it difficult to predict the timing
of the software that runs on this hardware, especially when the soft-
ware itself has many different execution paths. To fight this combined
hardware-software complexity that makes an accurate timing analysis in-
feasible, we have conceived a very simple software structure for real-time
tasks: We do not allow that decisions about the control flow are made
at runtime, i.e., all decisions are resolved in an off-line analysis before
In this paper we show that simple control structures generated before
runtime can as well be used within the operating system of an embedded
real-time system. In this way we make not only task timing but also the
timing of the operating system and thus the timing of the entire real-time
computer system fully deterministic, thus time-predictable. We explain
the principles and mechanisms we use to achieve this predictability and
show the results of an experiment that demonstrates the feasibility of
our concepts.
