The hwmon is a generic Linux kernel subsystem, providing access to hardware monitoring components like temperature or voltage/current sensors. Traditionally interfaced via external buses like I2C, many…

ARM-based platforms come in a range of processor configurations, and these platforms often have more than one ARM processor.  Traditionally these have been Symmetric Multi Processing (SMP) systems, where…

This blog covers three areas of GCC’s command line options: CPU, floating point and SIMD (Single Instruction, Multiple Data) acceleration.

This blog shows step-by-step how to build the UEFI software and debug it at source level, including all dynamically loaded modules (DLLs), using the ARM Development Studio 5 (DS-5) toolchain.

Embedded devices have rapidly evolved in the past decade. Although these devices are capable of running advanced web and desktop applications with sufficient performance, further improving the software…

IntroductionIn the information era with its increased use of mobile devices to communicate and access information, web browsers constitute the central component to navigate through the vast amount of information…

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…

DirectFB (Direct Frame Buffer) is a graphics library that is widely used in embedded systems, especially home market. More and more applications or libraries choose DirectFB as backend, such as Cairo,…

Great leaps in human knowledge are linked to advancements in tools. For software engineers the debugger is a cornerstone tool to create reliable products. We engage in a running battle fighting both 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…

This blog covers the use of two powerful debugging techniques — stack frames and instruction trace — to debug random or timing-related bugs on ARM processor-based targets.Timing-related and random bugs…

In this blog you will find information about semihosting, an implementation of the C library that uses a JTAG debugger to interface the world. Semihosting is very useful for board bring-up, as it works…

In this article we will go through the steps required to setup Linux on the PandaBoard using files supplied from Linaro and also the further steps required to setup Linux for use with Development Studio…

System-level Analysis with Performance Counters - This is my last post of this series (see Timeline analysis, Smart software profiling and Benchmarking if you missed previous posts), and you would expect…

Benchmarking -  ARM DS-5™ Streamline is designed for software and system analysis (see previous posts on Timeline analysis and software profiling), and that is where all its power features apply…

Smart software profilingFollowing 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™ Stre…

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…

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…
