+title: Trace, Profiling and Diagnostics Aggregator - TPDA
+
+description: |
+ TPDAs are responsible for packetization and timestamping of data sets
+ utilizing the MIPI STPv2 packet protocol. Pulling data sets from one or
+ more attached TPDM and pushing the resultant (packetized) data out a
+ master ATB interface. Performing an arbitrated ATB interleaving (funneling)
+ task for free-flowing data from TPDM (i.e. CMB and DSB data set flows).
