26.17 TPIU (trace port interface unit)

26.17.1 Introduction

The TPIU acts as a bridge between the on-chip trace data from the ITM and the ETM.

The output data stream encapsulates the trace source ID, that is then captured by a trace

port analyzer (TPA).

The core embeds a simple TPIU, especially designed for low-cost debug (consisting of a

special version of the CoreSight TPIU).
