New Armv9 CPU core

ARM processors touch 70% of the global population. From the edge to the cloud, Arm is on track to touch 100 percent of the world’s shared data. Arm has announced Armv9, its first new ARM architecture in a decade. Arm’s solution to the future needs of AI, security and specialized computing is v9 released at March 30, 2021. News highlights:

  • The new Armv9 architecture will form the leading edge of the next 300 billion Arm-based chips
  • Advances specialized processing built on the economics, design freedom and accessibility advantages of general-purpose compute
  • Delivers greater performance, enhanced security and DSP and ML capabilities

The latest Arm architecture updates promises to deliver the power of specialized processing with the economics, design freedom, and accessibility of general-purpose computing. Armv9 is promised to be code-friendly and secure. ARM has ongoing rollout of Armv9 to enabling partners to deliver best-in-class solutions for all workloads and applications and across all markets.

Armed for the Future: Armv9 Architecture Equips Chips with AI, Security, DSP Superpowers article says that in 2021 the keywords are artificial intelligence, the cloud, and security. Arm’s new Armv9 architecture directly enhances all of these and more thanks to what might sound like a paradoxical focus on specialized computing. Focusing first on security, Arm build on their hardware-enforced TrustZone technology with the new Confidential Compute Architecture (CCA), which provides an impenetrable firewall between apps running on the same OS, as well as ensuring the safety of data in transit from Arm-based server to Arm-based handheld. So we will see this new core in everything from smart phones to servers.

The updated architecture places a focus on secure execution and compartmentalisation. In addition to security features there are signal processing enhancements. Arm CPU and NPU (neural processing unit) devices are already replacing cloud-based AI infrastructure with low-power Edge compute, but enhancements to Matrix Multiplication (a key operation for machine learning) and new Advanced SIMD instructions and Scalable Vector Extension 2 (SVE2) technology boost not only ML but also DSP, VR and AR compute performance.

Arm broadens established footholds in the cloud through partnerships with Amazon (AWS Graviton processors), Microsoft (Azure Edge), VMware, and Ampere. In Armv9: The Future of Specialized Compute blog post Arm CEO Simon Segars explains why the launch of the Armv9 architecture signals a new era for Arm and its partners. We will have to wait for some time to see the silicon with the new core to become available.

    Arm unveils v9 architecture
    Arm has introduced the Armv9 architecture in response to the global demand for ubiquitous specialized processing with increasingly capable security and artificial intelligence (AI).

    Pervasive computing — IoT, edge, cloud, data center, and back
    Arm announced its Armv9 architecture, which is designed for secure, pervasive computing that can run in more types of AI systems. Because most data will be touching an Arm-based chip in the near future — whether on the edge, IoT, or data center — Arm enhanced the security, in addition to improving performance and AI/ML capabilities, according to a press release. Data is shielded through its Confidential Compute Architecture (CCA), which uses Realms — dynamically created shields that protects sensitive data and code while in storage, use, and transit. Microsoft Azure collaborated on Realms.

    Killer Screwdriver

    Neon tester/ terminal driver gets tested on a few thousand volts.
    Not a good prospect if you were on the end of it, and you had it in your hand and inadvertently made contact with a few thousand volts.
    Strongly advise to use a proper insulated screwdriver for terminals.
    Use a proper voltage tester like a fluke with 2 probes to get a definitive answer to weather there is voltage or not.
    Always ensure that your test equipment is rated for the voltage you want to test or work on.
    Where ever possible do not work on live equipment moving wires about.
    Play safe !

    Arm’s new chip architecture will power future devices, possibly including Apple’s

    Chip designer Arm Ltd. has announced its new v9 architecture, a design that could eventually appear in the Apple Silicon powering future iPhones, iPads, and Macs.

    The new Arm v9 focuses on three areas: performance, security, and machine learning (ML) capabilities. Arm says the design will provide more than a 30% CPU performance boost over the next two generations of mobile and infrastructure CPUs.

    AI is another critical area Arm targeted with its v9 design. The architecture’s new Scalable Vector Extension 2 (SVE2) technology will enhance ML and digital signal processing (DSP) for future devices.

    Arm’s SCE2 can improve processing for 5G systems, ML, voice AI assistants, and virtual and augmented reality.

    Security is the third pillar of Arm’s new design. Its Confidential Compute Architecture (CCA) “shields portions of code and data from access or modification while in-use, even from privileged software, by performing computation in a hardware-based secure environment.”

    The CCA will use a concept called Realms, a “region that is separate from both the secure and non-secure worlds.” For example, Arm says a business application could use Realms to protect sensitive data from the rest of the system “while it is in-use, at rest, and in transit.”

    ARMv9 gives 30%+ Performance Gains for future Apple Silicon & iPhones

    ARM V9 coming to Apple A15 & M2? Siri gets new voices and Apple TV’s getting a new remote. Then I’m answering your iCaveAnswers about AMD going ARM, iPhone 13 Colours, iPad 10, Tim Cook retiring and what MacBook to buy right now. So lets GO

    ARM has announced their V9 Architecture, and its the first major update in a decade. ARMv6 was the instruction set in the original iPhone, ARMv7 was the last 32 bit version that was abandoned after the iPhone 5, with the 64 Bit ARM 8 taking over for the 5S onwards.
    In terms of what ARM v9 means in broad terms, it’s about faster performance, better AI performance and Security.
    ARMv9 is focused on machine learning but will also benefit general purpose computing, AR, VR and 5G. And we’re already aware of Apple’s interest in AR and VR, as well as how real 5G got last year.

    CPU performance could improve by over 30% on ARMv9 and all existing software should run perfectly without modification as the standard is fully backward compatible, which given the current performance of Apple’s processors sounds pretty awesome!

    New Arm architecture brings enhanced security and AI to IoT

    The Armv9 architecture launched at the end of March, with the aim of enhancing AI processing in IoT devices. The need seems clear: the company estimates that 90% of new IoT applications will contain some kind of AI element. Among the applications expected to require AI are voice processing for device control, vision processing for industrial automation and consumer systems, and machine learning for robotics, autonomous mobile devices, and smart sensors. AI is also providing developers with an alternative to custom programming when adapting their device designs to specific use cases.
