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 […]

Armbian v25.2 and DietPi v9.11 released with updated Ubuntu and Debian-based Linux images for single board computers

Vendor-provided Linux images for single board computers are not always working optimally, so this post is a regular reminder that users may want to check out Armbian and DietPi projects mostly supported by the community but also backed by some of the vendors who offload some (repackaging) software work to them. Armbian and DietPi are separate projects, but this month, Armbian v25.2 and DietPi v9.11 were almost released simultaneously. I don’t report on each release (should I?), but they release an update every few months. The last time we had a look at both projects was in September 2024 for the releases of DietPi 9.7 and Armbian 24.8. Let’s see what the new releases have to bring. Armbian v25.2 Main changes: New Boards – Rock 2A and 2F, NanoPi R3S, Retroid Pocket RP5, RPMini, Rock 5T, GenBook, MKS-PI, SKIPR, Armsom CM5, NextThing C.H.I.P, Magicsee C400 Plus Rockchip 3588 Improvements – […]
