Whitepaper - ARMv8-M Architecture Technical Overview

The next generation of ARM Cortex-M processors will be powered by a new architecture version called ARMv8-M architecture. This document provides a technical overview of various enhancements in the new architecture, as well as an introduction to the security technology, called TrustZone for ARMv8-M. This document also introduces AMBA 5 AHB5 which enables security management at a system level, and covers various use cases of the new technology.
