Arm’s edge AI platform features the Cortex-A320 CPU and Ethos-U85 NPU, enabling on-device execution of models exceeding 1 billion parameters. The Armv9 platform enhances efficiency, performance, and security for IoT, while unlocking new edge AI applications through support for both large and small language models.

Built on the Armv9 architecture, the Cortex-A320 delivers 10× higher ML performance and 30% better scalar performance than its predecessor, the Cortex-A35. It also achieves an 8× ML performance gain over the Cortex-M85-based platform launched last year. Additionally, Armv9.2 offers advanced security features like pointer authentication, branch target identification, and memory tagging extension.

The Cortex-A320 pairs with the Ethos-U85 AI accelerator, which supports transformer-based models at the edge and scales from 128 to 2048 MAC units. To streamline edge AI development, Arm’s Kleidi for IoT compute libraries enhance AI an ML performance on Arm-based CPUs with seamless ML framework integration. For example, Kleidi boosts Cortex-A320 performance by up to 70% when running Microsoft’s Tiny Stories dataset on Llama.cpp.

Infineon’s PSOC 4 series microcontrollers now integrate capacitive, inductive, and liquid level sensing in a single device. The PSOC 4000T, powered by a 32-bit, 48-MHz Arm Cortex-M0+ processor, combines CAPSENSE capacitive sensing with Multi-Sense inductive sensing and non-invasive, non-contact liquid sensing.

Infineon says Multi-Sense inductive sensing offers greater noise immunity and durability than existing methods. Its differential, ratio-metric architecture supports new HMI and sensing applications, including touch-over-metal, force touch, and proximity sensing.

The PSOC 4000T’s liquid sensing uses an AI/ML-based algorithm that Infineon says is more cost-effective and accurate than mechanical sensors and standard capacitive solutions. It resists environmental factors like temperature and humidity and detects liquid levels with up to 10-bit resolution. It also rejects foam and residue and operates across varying air gaps between the sensor and container.

The fifth-generation CAPSENSE technology enables hover touch sensing, allowing interaction without direct button contact. Its always-on capability reduces power consumption by 10× while delivering 10× higher signal-to-noise ratio than Infineon’s previous devices.

The PSOC 4000T with CAPSENSE and Multi-Sense is available now. A second device, the PSOC 4100T Plus, offering more memory and I/Os, will gain Multi-Sense support in 2Q 2025.
