Architectures and Processors blog

There is currently a lot of talk around Advance Driver Assistance Systems (ADAS) in the car market. Car makers are trying to differentiate their vehicles to end customers by implementing more and more…

Abstract ARM Processor are becoming the part of the development and increasing the Ubiquitous computing environment. This family can role vital role for the sustainable development. In the developing…

With ARM entering the server space, a key technology in play in this segment is Virtualization. In this blog I will be taking a look at the Xen Hypervisor, which is now one of the Linux Foundation’s collaborative…

After a few years research and study about ARM, I was impressed by the ARM cortex, not just because it can be created as cheap as possible by a highly advance machine, but at the simplicity of the design…

1) Cortex-R processor are widely used across many embedded applications Often the Cortex-R Series are used in devices such as storage controller processors, LTE modems and industrial and automotive applications…

Several people have asked me for the following paper I presented in Embedded World 2014: ARM Cortex-M Processor based System Prototyping on FPGA Abstract Many SoC designers need to design FPGA prototypes…

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.

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…

This is the second part of a series of blogs about hardware coherency. This part talks about the implementation of hardware cache coherency and use cases.

Chinese Version中文版We live in a mobile world – A world where people connect from wherever they are and whenever they want to everything that matters in their lives. ARM has been part of this mobile world…

If you are a microcontroller designer working on Cortex-M processor based systems looking for an FPGA board for prototyping, I have a great news for you: ARM has released a new FPGA board, the Cortex-M…

You may have seen that ARM has been developing some low level trusted firmware to provide reference code that supports Secure World software on the latest v8A technology based chips.   The software is…

It often surprises me how many people believe that “ARM doesn’t do division” or “ARM cores don’t have divide hardware”. Of course, that used to be the case – up until the launch of the Cortex brand in…

A lot has changed in a year, and progress stops for no man or woman. I documented last year how to get a standard Linux distribution running on the ARM powered Samsung Series 3 Chromebook, those steps…

One of the most common classes of question in the ARM community which I answer is "How do I do <x> in ARM assembler?". While I am always happy to answer these questions, I thought it would be useful to…

By now, everyone knows that the ARM Cortex-A15 processor is ARM’s highest performance v7a ARM core to date. The Cortex-A15, along with the other ARM-based cores, are helping tablets surge a projected…

Trusted Labs have prepared a great document explaining the GlobalPlatform TEE security certification scheme.  As the importance of security grows this is likely to be an interesting option for silicon…

Over the last few weeks, there have been a number of very interesting and significant announcements from multiple companies with new initiatives based on ARM technology targeting designs for networking…

This year I presented "Extended System Coherency for Mobile and Beyond" on the fundamentals of cache coherency. This blog is the first in a series and starts with cache coherency fundamentals.
