It was always about the code (and where it would be used!) When I was a software developer I would often find that the project team I was in would try to guess how many devices the code would eventually…

Armv8 deprecates the use of the it instruction to make anything other than a single 16-bit instruction conditional. This affects many of the examples in this post.

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.

过去两年来，我们在这些博客中介绍了多种应用，其中，MaliTM-T600 系列能通过将应用中的计算密集型部分转移给图形处理器 GPU，其余部分继续在 CPU 上运行，来提高系统性能。在今年的 COMPUTEX 上，我们将发布强大的 ARM® Cortex®-A12、Mali-T622 和 Mali-V500 组合，为中价位智能手机系统级芯片 SoC 提供 ARM 异构计算的优势…

随着苹果公司的系列产品在市场上的推出，众多电子设备厂商发现，移动设备越变越智能，交互界面越来越人性化。电子设备不光要有硬件，同时需要有强大的软件。这对于移动设备的图形处理能力提出了新的需求。最新的硬件在CPU与GPU的配置上，开始逐步满足移动设备的需求，但是在软件上还没有一个成熟的解决方案。用户对于人性化，图形化，智能化的界面要求尤其强烈。成立于1998年的深圳盖亚信息技术有限公司抓住了这一市场契机…

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…
