Guidance For Using SystemReady On Automotive Platforms
By Arm - 10 Dec, 2025 - Comments: 0

Automotive platforms can significantly benefit from adopting the Arm SystemReady Devicetree Band as the basis for their platform firmware. By aligning with the SystemReady Devicetree Band and the recommended optional features in this document, platforms can support use cases such as secure boot and update, hardware discovery, power-state coordination, hardware fault detection, and system-level ... » read more

AIxCC 2025: What It Means For Device Security
By Jasper van Woudenberg - 06 Nov, 2025 - Comments: 0

The DARPA-sponsored Artificial Intelligence Cyber Challenge (AIxCC) culminated at DEF CON 33 this year, marking a moment where autonomous AI systems demonstrated they can both find and patch vulnerabilities at machine speed. Over two years, teams developed Cyber Reasoning Systems (CRS) designed to scan, prove, and fix bugs in open-source programs without human aid. In the final round, seven t... » read more

Integrated Modular Firmware Solutions: A Vital Component Of Custom Silicon Chiplet Architecture Designs
By Marc Meunier - 16 Oct, 2025 - Comments: 0

By Marc Meunier and Srini Narayana The shift from monolithic SoC designs to chiplet-based architecture isn’t just a packaging innovation. It’s a fundamental rethinking of how custom silicon is designed, manufactured, and deployed. This transition is driven by the growing impracticality of scaling large monolithic dies at advanced nodes. As die sizes increase, so do the costs, yield ri... » read more

Arm SystemReady Certification System Requirements Specification v2.1
By Arm - 07 Jun, 2023 - Comments: 0

Systems that are designed to “just work” for the end user (with the ability to install and run generic off-the-shelf operating systems out-of-the-box) need to follow a set of minimum hardware and firmware requirements to ensure compatibility. For hardware, the Arm SystemReady Program defines a common Base System Architecture (BSA) specification and a set of market-specific supplements. F... » read more

Secure Device Updates On Matter
By Nicolas Devillard - 09 Feb, 2023 - Comments: 0

There are many who share the Arm vision of smart connected devices enabling rapid innovation in our work and home in the coming years. Such connectivity promises to yield new applications for solving problems and improving lives. But onlookers are keen to see how the industry resolves a large obstacle to the next phase of digital transformation: how to keep these smart devices securely upd... » read more

Hidden Impacts Of Software Updates
By Ed Sperling - 10 May, 2022 - Comments: 0

Over-the-air updates can reduce obsolescence over longer chip and system lifetimes, but those updates also can impact reliability, performance, and affect how various resources such as memory and various processing elements are used. The connected world is very familiar with over-the-air (OTA) updates in smart phones and computers, where the software stack — firmware, operating systems, dr... » read more

Building Security Into ICs From The Ground Up
By John Koon - 05 May, 2022 - Comments: 0

Cyberattacks are becoming more frequent and more sophisticated, but they also are starting to compromise platforms that until recently were considered unbreakable. Consider blockchains, for example, which were developed as secure, distributed ledger platforms. All of them must be updated with the same data for a transaction to proceed. But earlier this year a blockchain bridge platform calle... » read more

Where Do Memory Maps Come From?
By Guillaume Boillet - 03 Mar, 2022 - Comments: 0

A memory map is the bridge between a system-on-chip (SoC) and the firmware and software that is executed on it. Engineers may assume the map automatically appears, but the reality is much more involved. The union of hardware (HW) and software (SW) demands both planning and compromise. The outcome of this merger will not be fully realized until the magical day when the system comes to life. T... » read more

Hardware Security Optimization With MITRE CWE
By Anders Nordstrom - 03 Mar, 2022 - Comments: 0

Whether you’re just starting to build out a hardware security program at your organization, or you’re looking to optimize existing hardware security processes, the MITRE Common Weakness Enumeration (CWE) database is an excellent resource to keep in your toolbox. What is CWE? A CWE is a type of vulnerability, or flaw, in the design of either hardware or software in embedded systems. Indi... » read more

Firmware Skills Shortage
By Brian Bailey - 25 Feb, 2021 - Comments: 0

Good hardware without good software is a waste of silicon, but with so many new processors and accelerator architectures being created, and so many new skills required, companies are finding it hard to hire enough engineers with low-level software expertise to satisfy the demand. Writing compilers, mappers and optimization software does not have the same level of pizazz as developing new AI ... » read more
