Trace Signals - ARM DSTREAM-PT Reference Manual

Trace signals

Some target devices can output high-bandwidth parallel trace data while the target application is running.
Capturing this data and decoding it in Arm Development Studio allows you to examine the sequence of
instructions, and changes in data, around a given point or trigger.
For CoreSight
continuous-mode Trace Port Interface Unit (TPIU) formatted trace, at up to 600Mbps per trace signal.
The Parallel Trace probe, in the DSTREAM-PT system, extends this functionality by supporting up to
32-bit wide TPIU trace.
The trace signals supported by DSTREAM-PT are:
TRACEDATA[0-31]
101714_0100_02_en
-compliant systems, DSTREAM-ST supports parallel trace capture of up to 4-bit wide
™
The Trace Data signals are outputs from the target and can be used to collect 1-bit to 32-bit trace
data.
