Architectures and Processors blog

Yesterday we released version 3.10.0 of Valgrind, a GPL'd framework for building simulation-based debugging and profiling tools.  3.10.0 is the first official release to support 64-bit ARMv8.  The port…

What is the connection between rugby football, interconnect and performance analysis kits?There is a seemingly never-ending march towards smaller, cheaper and more efficiency in complex chip design, and…

Embedded processors are frequently compared through the results of Power, Performance and Area (PPA) implementation analysis. jatinnmistry and I have created a whitepaper that describes the specific details…

The ARM® Cortex®-R family is perhaps the unsung hero of the ARM powered world, quietly running infrastructure from Hard Disk Drive and Solid State Drive controllers, through to mobile phone baseband processing…

Chinese Information  中文信息：参与ARM技术培训的新途径Just a short update to highlight an exciting new development. In response to demand, ARM has launched a limited program of public open-enrollment training courses…

Chinese Version 中文版： 简化ARM平台上的开发：针对多核SoC构建自定义调试和跟踪解决方案A study recently carried out by Cambridge University found that the global cost of software debugging has risen to the princely sum of $312 billion…

I have followed some tutorials on the internet and found one in particular quite interesting and didactic for those just starting to program ARM Bare metal. The Blog é Freedom Embedded | Balau's…

It has been a full seven months since AMD released detailed information about its Opteron A1100 server CPU, and twenty two months since announcement. Today, at the Hot Chips conference in Cupertino, CA…

This application note is intended to help you migrate software applications from ARMv5 to ARMv7-A/R. It describes the differences between ARMv5 and ARMv7, and explains the issues involved in migrating…

Arm has three series of microcontrollers, the Arm Cortex-A, Arm Cortex-R and Arm Cortex-M. In this blog we explore these and assembly programming.

The Cortex-A5 processor (launched in 2009) implements the ARMv7-A architecture profile and can execute 32-bit ARM instructions and 16-bit and 32-bit Thumb instructions. Here are the top five things to…

Read more about Cortex-M and learn five different things you didn't already know.

An interesting webinar on "Building a Customized Debug and Trace Solution for a Multi-Core SoC" is being organised on July 24, 2014, 2:00 PM EDT, where you can learn how to:Design and verify configurable…

Kicking off this week for the world of supercomputing is the 2014 International Supercomputing Conference in Leipzig, Germany. One of the major supercomputing conferences, ISC is Europe’s largest supercomputing…

There has been lots of interest in ARM Trusted Firmware.  We are aware that YouTube is unavailable to some parts of the world so you might like these links that should work anywhere:Go to the session link…

The ARM Trusted Firmware team have just released v0.4 under a permissive BSD license to enable the ARM ecosystem with a high quality reference implementation of:1. Secure Monitor Calls (SMC) Calling Convention2…

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…
