Here at ARM we continuously work to increase the quality of our driver software. Thorough testing is a significant proportion of our driver production process and its efficiency enables us to deliver drivers…

In this blog I will finish the construction of this abstract machine, forming the final component: a stereotypical Mali Midgard GPU programmable core.

If you didn't make it to the Linaro Connect in Macau earlier this month you may have missed Andrew Thoelke's excellent pitch on ARM Trusted Firmware.  ARM Trusted Firmware is low level, highly privileged…

A whitepaper that looks at TrustZone based Trusted Execution Environment (TEE) in context of the 4 compartment security model.  The second half looks at how a well designed Apps processor can use TrustZone…

ARM processors are increasingly used in automotive applications such as In-Vehicle Infotainment (IVI), Advanced Driver Assistance Systems (ADAS), powertrain, chassis and body control.

Welcome to my series of blogs on engineering software for accelerated systems!  Special-purpose hardware designed to execute certain computations (prominently, GPUs designed to execute graphics computations…

It’s that time of the year again where spring is in full force, the sun is shining, birds are chirping and this year’s college graduates are spreading their wings and sending out resumes.  Despite at least…

中文版 Chinese Version:“基准测试代表什么？”I’m asked quite a lot about how I feel about benchmarks. When I sit down to write these blogs I usually go searching for suitable quotes. For this one I found…

Continuing on from It’s Just Criminal! Examples of Performance Thrown Away in Real Apps (Part 1) lets look at more criminal behavior and for me what has to be the crime of the year... “Possession…

Every time I stand up at GDC and give a presentation on how to improve the performance of mobile applications there is always one person in the crowd that fills in the feedback form with the following…

Time and time again when I’m presenting at events I am asked the same questions: What does the future of mobile content look like? How much performance will content developers need? When will mobile devices…

You know those deep questions you get in philosophy like "If a tree falls in a forest and no one is there to hear it, does it still make a sound?", "What is the sound of one hand clapping?", "Why is there…

Arm Cortex-M processors offer versatile interrupt priority management but the multiple priority numbering conventions can lead to bugs. I explain the subject and cut through the confusion.

I have just returned from my third Mobile World Congress (MWC) in Barcelona and I have no doubt this year’s has been for me the best one so far! We are continuing to see a strong trend in independent third…

I can't imagine anyone reading this posting hasn't already read about the Apple "goto fail" bug in SSL. My reaction was one of incredulity; I really couldn't believe this code could have got…

中文版 Chinese Version: 面向可穿戴设备的蓝牙技术 Wearable technology certainly made a splash at CES 2014 in Las Vegas. Several industries such as healthcare, sport and fitness, gaming, and even fashion were demonstrating…

What exactly is rapid prototyping ?Sometimes we get some great ideas; some ideas are forgotten due to it took too long to build other ideas.But if we could just build our circuits as quickly as they came…

A great deal of attention at this January’s OCP Summit was focused upon ARM’s SBSA Server platform standardization announcement.  The importance of the SBSA to the ecosystem and our ARM partners cannot…

Another important milestone was reached recently for TSMC  and ARM when the teams taped out at the end of December 2013 (see block diagram) the first 64 bit ARMv8 processors in a big.LITTLE configuration…

This blog continues the development of this abstract machine, looking at the tile-based rendering model of the Arm Mali GPU family. I’ll assume you've read the blog on pipelining; if you haven’t I suggest…

The ARM® Cortex®-A Series Programmer’s Guide has proved to be a very popular addition to the ARM documentation set, and now also forms the reference textbook for the ARM Accredited Engineer(AAE) examinations…
