Key features of MCU-focused Arm's Cortex-M52 for edge AI; suggested migration from M33 and M4
Date: 11/12/2023
While most of the computer users hop in to cloud-based generative AI and LLM based systems for the AI processing requirements. It is to be noted that edge AI is also progressing equally well in offering AI computing at the edge-terminal itself particularly in cases of IOT, smart home automation, and also in industrial automation. There are significant advantages in having AI at edge, where you have high reliability and better privacy without any latency.
Arm is an edge perocessor core expert and is developing edge-AI capable processor cores for larger base of applications. The new Cortex-M52 from Arm offers below features and benefits:
The basic advantage of this processor core is its physical size. Targeting low cost IOT devices this processor core basically packs maximum performance in a smaller area for edge AI computing.
Arm Helium technology based Arm Cortex-M52 designed for AIoT applications that require a boost in digital signal processing (DSP) and ML performance without the cost overhead of dedicated DSP and ML accelerators at low price points and also without a dedicated NPU.
Cortex-M52 provides a simplified migration path from the Cortex-M33 and Cortex-M4.
Cortex-M52 is fully software compatible with Cortex-M55 and Cortex-M85.
Cortex-M52 delivers the flexibility needed to scale across a range of performance points and configurations.
Developers can benefit from an uplift in both ML and DSP performance, with up to 5.6x performance uplift for ML and up to 2.7x performance uplift for digital signal processing compared to previous Cortex-M generations.?
Cortex-M52 implements the latest security extensions for Armv8.1-M, including PACBTI and Arm TrustZone technology.
Cortex-M52 will accelerate the route to PSA Certified Level 2 silicon, enabling the next generation of PSA Certified devices.
"The Cortex-M52 CPU delivers higher levels of AI inference performance on the smallest devices" says Paul Williamson, SVP and GM of the IoT LoB, Arm in his article at:
