Armv8-M Architecture and Processors
Abstract
Armv8-M and Armv8.1 are the latest architectural specifications for Cortex-M processors. Together, they define additional security and high-performance compute extensions. Armv8-M introduces Arm’s TrustZone technology to Cortex-M processors. TrustZone is a hardware security model that forms the security foundation for IoT and connected devices. The Armv8.1 defines the Helium Vector Extension that provides the processing power required for Machine Learning and Digital Signal Processing algorithms.
