DSTREAM-HT Debug Adapter
DSTREAM-HT is a high-performance debug and trace unit, that supports high-speed serial trace ports to enable off-chip trace data bandwidth with fewer pins on the SoC compared to parallel trace ports. When combined with Arm Development Studio, it allows debugging through JTAG or Serial Wire Debug (SWD) interfaces while simultaneously collecting highly detailed instruction and data trace at up to 60 Gbps.
