Introduction to the Armv8.1-M Architecture

For the industry to scale to one trillion connected, smart and secure devices, embedded applications need a strong and intelligent foundation that delivers the required compute performance efficiently and cost-effectively. With small, embedded products growing exponentially, we need to ensure devices of the future deliver the very best performance and are managed securely.

The Armv8.1-M architecture is an extension of the current Armv8-M architecture that will bring enhanced compute performance for the next generation of embedded devices. This paper will explain the new features of the architecture, including a new M-Profile Vector Extension (MVE) called Arm Helium technology for the Arm Cortex-M series.
