Architectures and Processors blog

In this article, I will give an introduction of TEE (trusted execution environment) and ARM TrustZone based on my one and a half year experimentation on several ARM platforms when implementing T6.

With the first Cortex-A53 based SoCs due to ship in the coming months, and Cortex-A57 based designs to follow early next year, ARM gave us a quick update on performance expectations for both cores. Given…

Typically when teaching a class about embedded C programming, one of the early questions we ask is: Where does the memory come from for function arguments?

Smart sensors are far from a myth, it is already used in million of devices (e.g. your mobile phone might already contain several smart sensors). Traditionally a number of smart sensors are designed with…

Before we do a dive into the ACPI standard, let’s go back to what the main goal is for firmware. Utopia is to have a universal firmware solution which can boot and support any Operating System (open, propriety…

Take a closer look at the code size of ARM’s Thumb instruction set against the microMIPS32 instruction set.

Register now to join design experts from Nuvation, Altera and ARM (stefanrosinger, CPU Product Manager) for this free SoC FPGA design webinar on May 8 11:00 am PDT / 2:00 pm EDT.FPGAs leverage IP cores…

ARM has started what I find an interesting series of presentations giving facts about their products.Here is the list so far:Ten Things to Know About big.LITTLEFive things you didn't know about the ARM…

An inside look at some of the new 64-bit processors coming from ARM partners in 2014.  

Valgrind is a GPL'd framework for building simulation based debugging and profiling tools.  The best known of these is Memcheck, a memory error detector, but in fact it is only one of eight tools in the…

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.
