This thesis discusses the transformation of hardware events to system events
for \gls{osek} compliant real-time \glspl{os}.  Hence, the parts of \gls{osek}
that are relevant for this thesis are described in the following.

Additionally, a well-defined format is required to represent the resulting
traces consisting of entities on system level.  The \gls{btf} format which is
discussed in \autoref{chapter:btf} is used within the context of this work.
