DSTREAM-ST is a debug and trace hardware unit that enables software debug and optimization on Arm® processor-based targets.

DSTREAM-ST provides an interface between a host such as Arm Development Studio and an Arm processor-based target using a hardware interface such as JTAG or Serial Wire Debug (SWD). It also enables the collection of narrow-port (4-pin) parallel streaming trace from the device for non-intrusive debug and code optimization.

This chapter describes the DSTREAM-ST hardware.
