The document discusses several advanced use cases for profiling applications using the XDS560 Trace tool and Advanced Event Triggering (AET) logic on Texas Instruments processors, including interrupt profiling to analyze interrupt servicing times, statistical profiling to identify functions consuming the most cycles, thread-aware profiling to generate a cycle-accurate execution graph of thread-based applications, and generating a thread-based dynamic call graph from captured trace data.
