2.3.4. Multi source trace in a multi-core system

Figure 2.9 shows a system with a core and a third party DSP. A third smaller subsystem supports merging of multiple CoreSight ATB busses into a single trace stream. Figure 2.9 also shows tracing of instrumented code using the STM.

This system requires bridges to support access through the DAP to the separate core and DSP subsystems.

Note

There are many alternative configurations possible with this set of components. The configuration Figure 2.9 shows does not necessarily correspond with the best configuration to meet your specific requirements.
