This article introduces the shifting operations provided by Neon, and shows how they can be used to convert image data between commonly used color depths.

Version 3.6.0 of Valgrind was released a couple of weeks ago. The largest change this release is the addition of support for Linux running on ARM. Learn more about the release in this blog.

In this post, I will be introducing a few concepts and explain the reasons behind them. In future posts, I will follow up with practical examples.

My previous post provided an introduction to memory access ordering. It did not however, provide any solution to the problem. This post covers barrier use within the Linux kernel.

On June 29, 2007 -- the original iPhone went on sale and unleashed an unrivaled period of creative innovation and destruction in the mobile phone business.  In case you have forgotten, the original iPhone…

I have a confession to make... I started writing this post in November 2011, but in the excitement of the events at the time, I left it unfinished... until today. This morning I stopped at a local supermarket…

Wouldn't it be great if I could transmogrify the PC to become an intelligent network of specialized components? The goal would be to create a much more efficient computation system marrying critical software…

Since you're reading this blog, it's fairly likely you're technically minded and would've heard of contact-less payment cards. These smart-chip enabled cards promise to speed checkout for…

I've always wanted a Smartphone that can be an abstraction of me. This is driven by my belief that there are people who like writing diaries and those who do not. I've been waiting for a device for…

As you may be aware, my ARM-Powered LEGO robotic Rubik's Cube solver "Speedcuber" was demonstrated live at Mobile World Congress '10 in Barcelona in February this year (actually it almost…

After the video of my most recent Arm-powered Android LEGO Speedcuber robot became so popular, I thought that it would be a while before I was involved in creating another. I should have learned from previous…

The 180nm node of today is nothing like the 180nm node of 2004. In fact the market opportunity for the 180nm node is bigger today than at any time in the past.

One of the key challenges faced by the semiconductor industry today is balancing the growing, yet conflicting demand for mobile devices featuring both high performance and long battery life. Last week…

You don't need a graphic like this one to know that multi-core SoC designs are here to stay.  This one happens to be based on ARM's AMBA® 4 ACE architecture, which is particularly effective…

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…

An SMM is a Soft Macrocell Model which is an FPGA implementation of an ARM processor, built with ARM development boards. Life with an SMM, would be much easier, at least from an engineer's perspective…

Using power management features of complex SoCs (system on chip) can be difficult due to the complexity of the design and multiple power domains. In this blog I discuss the power management hardware features…

Smartphones are now one of the most important consumer electronics devices globally. Smartphone volume shipments are growing at a very healthy rate and are expected to exceed a billion units per annum…
