Enhancing the Capabilities of the Smallest Devices
Arm Helium technology is the M-Profile Vector Extension (MVE) for the Arm Cortex-M processor series. Helium is an extension of the Armv8.1-M architecture and delivers a significant performance uplift for machine learning (ML) and digital signal processing (DSP) applications.
With Helium, Arm Cortex-M processors can manage the compute challenges in many applications, such as audio devices, sensor hubs, keyword spotting, and voice command control, power electronics, communications and still image processing.
There are similarities between Helium and the Advanced SIMD technology for Arm Cortex-A processors, which is called Neon. However, Helium has been designed from the ground-up for efficient signal processing performance in small processors, and provides many new architectural features to unlock new applications.
Many OEMs, software providers, and tools partners within the Arm ecosystem are supporting the development of Helium and are ready to build the next wave of compute.
Helium provides up to five times the performance improvement for common signal processing tasks, and up to 15 times performance uplift for machine learning.
Helium works together with TrustZone to make an excellent base for implementing Platform Security Architecture (PSA) compliant systems.
Developers can benefit from a simple programmer’s model and one toolchain to reduce development efforts and costs.

Arm Neon Technology
Neon technology is an advanced SIMD architecture extension for the Arm Cortex-A series and Cortex-R52 processors. The architecture extension improves the multimedia user experience across many applications.
CMSIS
The Cortex Microcontroller Software Interface Standard (CMSIS) enables consistent device support and simple software interfaces to Cortex-M processors and their peripherals. This simplifies software reuse, reduces the learning curve for microcontroller developers, and reduces the time to market for new devices.
Platform Security Architecture
The Platform Security Architecture (PSA) is a common industry framework for IoT devices. PSA helps developers define a consistent level of security by providing principles and deliverables, including threat models, architecture specifications and open source firmware. A key security goal outlined in PSA is isolation—exactly where Arm TrustZone provides a perfect implementation.
TrustZone for Cortex-M
Arm TrustZone technology provides system-wide hardware isolation for trusted software. It creates an isolated secure world to provide confidentiality and integrity to the system, protecting almost any asset from specific attacks.
Armv8.1-M Architecture
Armv8.1-M takes the Armv8-M architecture to new performance levels for the smallest devices. The architecture includes TrustZone and the M-Profile Vector Extension (MVE) used in Helium, and is a primary target of the PSA framework.
