ARM TrustZone technology is a system-wide approach to security for system-on-chip (SoC) designs. It is hardware-based security built into the heart of CPUs and systems and used by semiconductor chip designers…

The Arm v8-A architecture continues to evolve, with the additions developed through 2016 collectively known as Armv8.3-A. In this post we go through these in detail.

A great deal of cyber ink has been spilt on the subject of Internet of Things - on the promise, the hype, the frustration that it’s not quite there yet. The entire concept of IoT combines sensory, connected…

Learn the five key features of the Arm Cortex-M33 processor, from co-processor interface for extensibility to DSP extension.

October 19, 2004 was a date like any other, and will probably not mean much to most people. However, if you are part of the Embedded community, that precise date was transformational for the microcontroller…

Prototyping an ARMv8-based design is similar to prototyping any other design.  FPGA prototyping for these types of application is generally used to validate the hardware quickly to head into the software…

ARM Cortex-M23 is the smallest and most energy efficient processor with TrustZone technology. Based on the ARMv8-M baseline architecture, Cortex-M23 is the ideal processor for constrained embedded applications…

ArmTechCon 2016 is nearly upon us, and there’s so much high quality technical content in the conference programme and exhibition floor that the only difficulty you’ll have is choosing what to attend

Open standards foster innovation, collaboration and choice. This blog discusses how 3 open interconnect standards, AMBA, CCIX and Gen-Z, complement each other within the datacenter.

At the Linley Processor Conference earlier this week, I had the opportunity to present the challenges facing architects who are building hardware for distributed cloud intelligence. I also discussed how…

A few weeks ago VORAGO Technologies issued a press release to announce that our VA10800 microcontroller had just surpassed 4000 hours of successful operation at 200C.

Functional safety is about ensuring that products operate safely and do so even when they go wrong. My colleague hopkins shares some insight on why you can’t choose to ignore it.

Arm Cortex-R52 addresses increases sophistication in safety applications which need higher levels of performance, greater support for functional safety and software separation.

The Cortex-M family has 5 processors. This whitepaper compares their features and highlights considerations for selecting the right processor for you.

The cat is out of the bag. There has been a lot of speculation around Apple’s plans to remove the headset jack for the iPhone 7. The recent announcement confirming this will now lead to innovation and…

Space radiation can cause different types of problems in an IC that are manifested as latch-up or Single Event Upsets (SEU). Latch-up can be immunized against by hardening the chip with a process enhancement…

Recently I spoke about a LZ4 decompression routine I converted from 6502 code into a Arm Cortex-M0 code. I could not find my decompression routine, so I decided to convert it again. The result is in this…

In this post I show you some tips and tricks when writing assembly code for Cortex-M0 and Cortex-M0+.

Chinese version(中文版):让下一代智能互联嵌入式应用开发更简化 (Editor's note: This article was originally published February 2015 in RTC Magazine and has been updated with new product information. The original article can…

Today we have exciting news: ARM and Intel Custom Foundry have announced an agreement to accelerate the development and implementation of ARM SoCs on Intel’s 10nm process. Specifically, we are making ARM…

Below, I suggest a list of books and papers about the Arm architecture.
