+\chapter*{Abstract}
+
+Embedded real-time multi-core systems must adhere to strict timing requirements
+in order to guarantee correct execution.  Timing requirements are specified to
+document system execution paths that are safety critical with respect to the
+timing behavior of an application. 
+
+Via tracing it is possible to validate the fulfillment of timing requirements
+in the native environment of a microcontroller.  However, trace tools produce a
+trace on hardware or software level, whereas requirements are specified on
+system level.  A transformation of the former to the latter is required to
+close this gap.
+
+Additionally, not all trace techniques are capable of producing results
+suitable for the real-time analysis of embedded applications.  Most techniques
+are not sufficient for one or several reasons: limited trace duration,
+inadequate number of recordable objects, and limited timing accuracy.
+
+Therefore, this thesis examines different trace techniques and shows why
+hardware tracing is the most sufficient for real-time analysis.  Next, the
+coherence between hardware, software, and system level entities is examined.
+Based on the results a mapping from software level to system level is
+introduced and validated.  
+
+The thesis concludes that it is possible to record cycle accurate system traces
+of arbitrary length via hardware tracing.  However, this requires detailed
+knowledge about hardware tracing and the operating system underlying an
+application.
