I am writing this short blog to help illustrate a great feature we have added to DS-5, available in version 5.19 and later. You can always get the latest version of DS-5 here. We have a new MMU view, as well as associated command line (CLI) commands to…
This blog has been written before but quite a few things have improved in the ease of use and breadth of support of Streamline use on Android in the past few years. For starters, Mac OS X is well supported. Now all three major development platforms (Linux…
For those of you who don’t already know about mbed, it is an open-source, ARM-based hardware and software platform designed for professional rapid prototyping of products and mass production. Since joining the mbed team this past March, I get asked…
在上篇文章中介绍如何利用Fast Model搭建自己的CPU后,很多朋友进行了尝试,生成了自己的CPU,并进行了一些简单的代码调试,但是大家很快发现,Model Debugger调试能力有限。今天就来说说如何利用功能强大的DS-5对自己搭建出来的Model进行开发调试,调试对象可以是操作系统,驱动,应用程序,凡是可以在CPU上执行的代码都可以在Model上用DS-5进行调试。特别是对于一些安全/虚拟化相关的应用和OS,因为有Trace的帮助,在Model上进行开发远比实际芯片简单。
第一步要把你的Model编译成可执行文件…
Note this blog is only valid for Linaro distributions up to 2014. Newer distributions support AEMv8 Base Model as supplied with DS-5 5.24 and later. For information on this model, see here.

ARM is constantly providing updates to our DS-5 toolchain, and details of these updates are provided in the change log. When you purchase the tools, you will receive either a term or perpetual license depending on what you purchased, as well as support…
ARM® Compiler 6 is the next generation C/C++ compilation toolchain from ARM, based on Clang and the LLVM Compiler framework. Version 6.00 of the toolchain provides architectural support for v8 of the ARM Architecture and alpha support for v7-A. It…
Over the first few blogs in this series I have introduced the high level rendering model which the ARM Mali "Midgard" GPU family uses. In the remainder of this series I will explain how to use DS-5 Streamline, a system-level profiling tool…
ARM Compiler 6 is now available, bringing to you a modern, extensible compiler architecture for the next generation of ARM processors. Version 6 of the ARM Compiler adopts the Clang and LLVM compiler framework, which is swiftly gaining momentum as the…
Streamline, the profiling tool in DS-5, is a powerful tool for analysing system behaviour with proven results at both macro (system level interactions) and micro (CPU code hotspots) levels.
Streamline is also an excellent way to explore a…
In this article I will explain how ARM® uses FPGA boards during the development of new cores to validate the design and how this technique is particularly useful to reduce project time and costs, giving an effective competitive advantage in the market…
I am an FAE at ARM, and part of my job is to support users bringing up new silicon and hardware platforms, so that they can start to develop software on them. For this task, I use…
This blog is for those of you who spend hours every day developing and debugging software, and have experienced the frustration that comes with the question “how on earth did my software get here?”
This is actually a fairly common situation…
Over the past few months, I’ve been working on a Real Time Operating System (RTOS) for the ARM® Cortex®-A9 processor, ported from the Keil® RTX RTOS for Cortex-M series of processors. In this blog, I’d like to share with you how I…

本文讲述如何设置Android手机来运行ARM Streamline性能分析器的各项步骤。 对于运行ARM Linux或Android原生应用程序和代码库的手机来说,ARM Streamline性能分析器是一款系统级的可视化分析工具。它结合了ARM Linux内核模块、守护程序以及图形用户界面,可将系统跟踪和采样数据转换为以可视化和统计式的报告来呈现数据。
The need for quality professional tools for cross platform development when battling obscure software bugs and performance issues cannot be understated. With the ARM® Development Studio 5 (DS-5™) Community Edition (CE) we deliver some of the…
Here at ARM, a colleague recently wanted to port Linux to a prototype of a new high-performance Cortex-A9 based platform. To develop and debug this port, he needed to be able to set breakpoints, view registers, view memory, single-step at source level…
Following up from previous post (Software Optimization: Four real-life Streamline use cases (Part 1): Timeline analysis), I will talk about the most basic use of ARM DS-5™ Streamline, software profiling. Streamline captures…
Here at ARM's System Design Division almost every time we introduce someone to the ARM® DS-5™ Streamline performance analyzer we end up being asked, so how much faster can my system run?' Normally we respond with a smile and explain that…
The ARM® Development Studio 5 (DS-5™) Community Edition (CE) has been extended to support the community of ARM Embedded Linux users, and it now works on Apple Mac hosts too! DS-5 Community Edition is available as a free download from…
