Exploring the Versatility of Arm Cortex Processors

On February 12, 2025 in All, Computing, General by Adam Taylor

There are approximately 38 Arm processors for every single person on the planet. With such an influence in the computing world, let’s look closer at the most popular instruction set architecture (ISA) ever produced.

Introduction to Embedded Python

On October 27, 2021 in All, Maker, Open Source by Mike Parks

The Python programming language is available in various implementations geared specifically towards embedded firmware developers. Each implementation attempts to be compliant with CPython; however, each has unique design-driven attributes that should be understood.

IoT Security by Design

On November 8, 2019 in All, Computing, IoT, Sensors, Wireless by Steven Keeping

The data carried across the IoT is valuable, and the unscrupulous will find and exploit any weakness to get hold of it. That makes protecting the trillion devices forecast to comprise the IoT by 2025 a tall order. Trusted Execution Environments offer a simple and cost-effective start.

Achieving Security Requires Much More Than Just Robust Technology

On September 28, 2018 in All, IoT, Security by Stephen Evanczuk

Although systems developers can draw on robust security technologies, effective security requires a combination of technologies, practices, and policies—and acceptance by each stakeholder of their own role in maintaining security.

New Ultra-Low-Power Benchmark

On June 4, 2014 in Low Power by John Donovan

As an editor I’ve been on the receiving end of a lot of specmanship, which is why I always look to datasheets, though meaningful comparisons of seemingly similar MCUs between different vendors are hard to construct, especially since overall energy consumption is so application specific. As Markus Levy of the Embedded Microprocessor Benchmark Consortium (EEMBC) remarked to me last week, “Datasheets don’t lie, they just present [information] the way they want to present it.”
