2.3.2. Single source trace

Figure 2.7 shows single core trace using the CoreSight infrastructure. The CoreSight-compliant ETM outputs directly to a TPIU for direct output of core trace off-chip. The tracing of only a single trace source enables you to configure the TPIU in bypass mode because source IDs do not have to be embedded in the trace data. You can add a CoreSight ETB and replicator to provide on-chip storage of trace data.
