Arm Cortex-A320 low-power CPU is the smallest Armv9 core, optimized for Edge AI and IoT SoCs

Arm Cortex-A320 is a low-power Armv9 CPU core optimized for Edge AI and IoT applications, with up to 50% efficiency improvements over the Cortex-A520 CPU core. It is the smallest Armv9 core unveiled so far. The Armv9 architecture was first introduced in 2021 with a focus on AI and specialized cores, followed by the first Armv9 cores – Cortex-A510, Cortex-A710, Cortex-X2 – unveiled later that year and targeting flagship mobile devices. Since then we’ve seen Armv9 cores on a wider range of smartphones, high-end Armv9 motherboards, and TV boxes, The upcoming Rockchip RK3688 AIoT SoC also features Armv9 but targets high-end applications. The new Arm Cortex-A320 will expand Armv9 usage to a much wider range of IoT devices including power-constrained Edge AI devices. Arm Cortex-A320 highlights: Architecture – Armv9.2-A (Harvard) Extensions Up to Armv8.7 extensions QARMA3 extensions SVE2 extensions Memory Tagging Extensions (MTE) (including Asymmetric MTE) Cryptography extensions RAS extensions […]

Toradex launches its first SMARC modules with NXP SoCs for improved compatibility and supply chain

Toradex SMARC modules with NXP i.MX 8MPlus and i.MX 95

Toradex has introduced its first SMARC-compliant system-on-modules (SoMs) with the SMARC iMX8M Plus and SMARC iMX95 SoMs based on NXP i.MX 8M Plus and NXP i.MX 95 SoC respectively. The company has made proprietary system-on-modules for years with the Colibri, Apalis, Aquila, and Verdin families. Those typically are cost-optimized and use most or all I/Os from the selected SoC, but customers are tied to one supplier: Toradex. To offer more flexibility, the company decided to introduce its first standardized system-on-modules by selecting the SMARC 2.2 standard for compatibility with existing SMARC-compliant carrier boards and adding the Swiss company as an alternative supplier. Highlights of the SMARC iMX8M Plus module: SoC – NXP i.MX 8M Plus CPU Quad-core ARM Cortex-A53 application processor @ 1.6 GHz Arm Cortex-M7 real-time core @ 800 MHz GPU – Vivante GC380 2D GPU and GC7000UL 3D GPU VPU – 1080p60 video decoder & encoder AI accelerator […]

FOSDEM 2025 schedule – Embedded, Open Hardware, RISC-V, Edge AI, and more

FOSDEM 2025 will take place on February 1-2 with over 8000 developers meeting in Brussels to discuss open-source software & hardware projects. The free-to-attend (and participate) “Free and Open Source Software Developers’ European Meeting” grows every year, and in 2025 there will be 968 speakers, 930 events, and 74 tracks. Like every year since FOSDEM 2015 which had (only) 551 events, I’ll create a virtual schedule with sessions most relevant to the topics covered on CNX Software from the “Embedded, Mobile and Automotive” and “Open Hardware and CAD/CAM” devrooms, but also other devrooms including “RISC-V”, “FOSS Mobile Devices”, “Low-level AI Engineering and Hacking”, among others. FOSDEM 2025 Day 1 – Saturday 1 10:30 – 11:10 – RISC-V Hardware – Where are we? by Emil Renner Berthing I’ll talk about the current landscape of available RISC-V hardware powerful enough to run Linux and hopefully give a better overview of what to […]

Arduino Core for Zephyr beta released – Let’s give it a try!

Last July, Arduino announced plans to switch from the soon-to-be deprecated Arm Mbed to Zephyr RTOS, and the company has now outed the first beta release of “Arduino Core for Zephyr OS” for a range of boards. From the user’s perspective, this should not change anything. However, there are massive changes under the hood and Arduino sketches are built and executed differently with the Arduino Core for Zephyr. Some highlights of the new Zephyr-based Arduino core implementation include: Dynamic sketch loading – Sketches are compiled as ELF files and dynamically loaded by a precompiled Zephyr-based firmware. Zephyr subsystems support threading, inter-process communication, and real-time scheduling. Fast compiling and smaller binaries since a thin layer of user code and libraries are compiled, while the rest of the ZephyrOS is already binary. You can get started straightaway with the code and instructions on GitHub. You’ll need Arduino 2.x.x for this to work. […]

NXP i.MX 94 octa-core Cortex-A55/M33/M7 processor targets Edge AI industrial and automotive applications

NXP i.MX 94 is an octa-core Arm SoC with up to four Cortex-A55 application cores, two Arm Cortex-M33 real-time/functional safety cores, two Arm Cortex-M7 real-time/functional safety cores, and an NXP eIQ Neutron NPU designed for Edge AI industrial and automotive applications I initially thought it would be a cost-down version of the NXP i.MX 95, and while it shares many of the same features, it’s more an application-specific processor designed specifically for industrial and automotive applications, lacking a 3D GPU, camera input interfaces, a MIPI DSI display interface, and 10GbE networking, but increasing the number of real-time cores (at the cost of application cores) and adding several networking features such as an Ethernet time-sensitive networking (TSN) switch, 2.5GbE interface, an Ethercat controller, and support for industrial protocols like Profinet or OPC-UA FX. NXP i.MX 94 specifications: CPU Up to 4x Arm Cortex-A55 cores 2x Arm Corex-M7 cores, one for functional […]
