ARM DSTREAM High Performance Debug & Trace

ARM DSTREAM High Performance Debug & Trace Image (View Larger ARM DSTREAM High Performance Debug & Trace Image)
The DSTREAM High-Performance Debug and Trace unit enables software debug and optimization on any ARM processor-based hardware target. DSTREAM extends the functionality of ARM RVI and ARM RVT2 with faster memory download and trace capture, as well as wider support for physical debug and trace interfaces.

DSTREAM enables the connection of DS-5 Debugger to ARM-based devices via JTAG or Serial-Wire Debug (SWD). DSTREAM uses FPGA acceleration to deliver high download speeds and fast stepping through code on single and multi-processor devices.

The Debug Connection You Can Rely On

With features such as accelerated hardware bring-up for many development platforms and open debug interface for use with third-party tools, DSTREAM is a comprehensive solution for development and debug of complex SoCs.

Trace is an essential tool for the resolution of complex software/hardware and timing-related issues, as it enables post-analysis of a software execution without the need for any software or hardware instrumentation. The 4 GB trace buffer on DSTREAM enables high-bandwidth trace for long periods of time, providing further visibility of how the software is executed on the target.

DSTREAM ships with powerful software utilities to assist with SoC bring-up and hardware validation. It also provides interfaces for third party and custom tools.
