An article from Semicast Research, published in Design & Reuse in January 2017, described Cortex-M23 and Cortex-M33 as “Born Secure”. I believe that this statement says something crucially profound…

The Statistical Profiling Extension is an optional feature in ARMv8.2. This article will provide an overview of the Extension, describe how it works, and the advantages it provides over other profiling…

Bluetooth-enabled insulin pens, like the one pictured above, conveniently record blood glucose levels and insulin delivery dosage, then transmits this data to the user’s smartphone via Bluetooth. This…

The ARM Cortex-M0 based VA10800 microcontroller has been qualified and is rated for operation at 200˚C.

A give-away of leading-edge technology devices always offers an opportunity to settle a bar bet: What’s the hottest gadget of the year?

The Smart Home market is now at an inflection point. This whitepaper addresses how artificial intelligence and machine learning are used in the Smart Home market focusing on sound recognition.

Arm TrustZone brings lightweight compartmentalisation to the M-profile with Armv8-M security extensions. Compartmentalisation is a technique that separates code from important data or permissions, improving…

Bluetooth Low Energy Bluetooth low energy (LE) is the power- version of Bluetooth that was built for the Internet of Things (IoT). The power-efficiency of Bluetooth® with low energy functionality makes…

ARM Physical IP for TSMC 7nm process technology now available Gone are the days when FPGAs were used primarily for prototyping. Today, developers can drive quickly and cost-effectively into IoT, embedded…

Have you ever been in a situation where you successfully validated your algorithm and asked yourself: is there a hardware platform with DSP capabilities so I can get my embedded project to market quickly…

For a beginner new to Arm based microcontrollers, it can sometimes be a little difficult knowing where exactly to start but this post will help you.

How to measure the impact of branch prediction for Cortex-R7 and Cortex-R8.

As we see the spectacular growth in connected devices required in low-power environment, manufacturers are turning to Arm Cortex-M4 and Cortex-M7 processors.

The main problemWhen assembling your first programs with AS, and linking it to external libraries like this :armv7a-hardfloat-linux-gnueabi-as -o test.o test.Sarmv7a-hardfloat-linux-gnueabi-ld.gold --hash…

If you're using Cortex-M0+, I bet you miss some instructions from the more capable Thumb-2 instruction set. At least occasionally you have searched for routines from various places: books like Hacker…

ARM Cortex-M23 and Cortex-M33 processors, announced recently at ARM TechCon 2016, both integrate a new Memory Protection Unit (MPU). This optional MPU is based on an updated ARM Protected Memory System…

ARM recently announced the first two processors using the ARMv8-M architecture, ARM Cortex-M23 and Cortex-M33. ARM TrustZone for ARMv8-M adds security features to these cores that allow applications and…

If someone offered to sell your business server-compute cycles for one-tenth the going price, you might think there was a catch. But in this case you’d be wrong. Nathan Goulding is the senior vice president…

This week, we’ve been enjoying the temperate climate in Lowell, MA, while our ARM Cortex-M0 microcontrollers have been weathering a storm of radiation in the ‘Gamma Cave’ at UMass.

The next generation of Cortex-M processors are powered by Armv8-M architecture. This blog is a technical overview of enhancements in the new architecture and an introduction to TrustZone for Armv8-M.

IoT refers to thousands of diverse market segments that are now using connected intelligent devices: from IoT nodes with rich user interfaces, to tiny sensors that are powered only by energy that is harvested…
