Arm releases Cortex-M52 core, allowing AI to enter more economical, lower-power devices

Arm today announced the Cortex-M52 core, which is designed for AIoT applications. The new core features performance improvements in DSP and machine learning (ML) and lower costs. Arm’s partners are expected to launch related products in 2024

According to reports, Cortex-M52 MCU can promote its ML functions through price advantages, allowing low-cost, low-power devices to also have artificial intelligence computing Force

Compared with previous generations of Cortex-M series products based on the Armv8.1-M architecture, the ML performance of Cortex-M52 can be improved by up to 5.6 times, and the DSP can be improved by up to 2.7 times.

Please note: Cortex-M52 was previously known as "Star" STAR-MC2 in the Chinese market, which was developed by Arm and Anmou Technology The Arm Helium technology of Cortex-M52, a product jointly developed by the engineering team, can provide significant performance improvements for small, low-power embedded devices, and can deploy more computing-intensive devices on the terminal without the need for a dedicated NPU. ML Inference Algorithm

Arm said that Cortex-M52 achieves the lowest area and power consumption among all Cortex-M processors supporting Helium technology, providing enhanced AI capabilities for lower-cost IoT devices .

Additionally, Cortex-M52 offers a simplified migration path from Cortex-M33 and Cortex-M4 to address a variety of AIoT application needs such as automotive and industrial control, predictive maintenance, and wearable sensor fusion.

Thanks to this, Cortex-M52 can provide scalable flexibility across a range of performance points and configurations, while delivering DSP capabilities without the need for a separate processing unit, thus saving chip area and cost.

In addition, Cortex-M52 also supports the latest Armv8.1-M architecture security extensions, including pointer verification and branch target identification (PACBTI) And Arm TrustZone technology

Arm said that Cortex-M52 will also help accelerate the launch of PSA Certified Level 2 certified chips, thereby enabling the next generation of PSA Certified certified devices.
