ARM DS-5 Development Studio

The reference software development tool suite for ARM processors

Developed by ARM Architecture experts, the ARM DS-5™ toolchain enables engineers to develop robust and highly optimized embedded software for ARM application processors, such as the Cortex™-A series, Cortex-R real-time processors and other ARM embedded processors. The DS-5 toolchain comprises tools such as the best-in-class ARM C/C++ Compiler, a powerful Linux/Android™/RTOS-aware debugger, the ARM Streamline™ system-wide performance analyzer and real-time system model simulators, all conveniently packaged in a user friendly integrated development environment (IDE) based on the Eclipse.

Debug Adapters

The ARM recommends the DSTREAM™ High Performance Debug and Trace Unit for fast and reliable JTAG debug connection and non-intrusive instruction and instrumentation trace. For users' convenience, the Keil® ULINKpro family and the legacy RealView ICE (RVI™) unit are also compatible with DS-5 for run-control debug.


  • Code download at up to 2.5 MB/s
  • 4 GB built-in trace buffer
  • Ethernet and USB 2.0 connections to host
  • Single firmware for all ARM processors


  • Code download at up to 1.0 MB/s
  • Support for ARM® Cortex®-M, Cortex-R and Cortex-A devices
  • Compatible with DS-5 and Keil® MDK-ARM
  • USB 2.0 connection to host

Power and Energy Analysis

The ARM Energy Probe is a simple, standalone hardware unit that connects to the ARM Streamline Performance Analyzer to display voltage, current and power measurements alongside other system performance metrics and software profile.

Energy ProbeEnergy Probe

  • No additional debug hardware required
  • 3 independent channels 
  • USB 2.0 connections to host

Simulation Models and Development Boards

ARM offers both virtual and physical development platforms that allow programmers to start coding, testing and debugging software for ARM platforms before the target hardware is available.

Fast ModelsFast Models

  • Virtual ARM platform on Windows or Linux hosts
  • Execution speeds comparable to the actual hardware
