Overview of this book

Embedded Systems Architecture begins with a bird’s-eye view of embedded development and how it differs from the other systems that you may be familiar with. This book will help you get the hang of the internal working of various components in real-world systems. You’ll start by setting up a development environment and then move on to the core system architectural concepts, exploring system designs, boot-up mechanisms, and memory management. As you progress through the topics, you’ll explore the programming interface and device drivers to establish communication via TCP/IP and take measures to increase the security of IoT solutions. Finally, you’ll be introduced to multithreaded operating systems through the development of a scheduler and the use of hardware-assisted trusted execution mechanisms. With the help of this book, you will gain the confidence to work with embedded systems at an architectural level and become familiar with various aspects of embedded software development on microcontrollers—such as memory management, multithreading, and RTOS—an approach oriented to memory isolation.

ARMv8-M is the newest architecture defined by ARM for modern microcontrollers. It extends and completes the capabilities of its predecessor, ARMv7-M, by integrating several new features. The most important improvement for this novel architecture design is the possibility to implement a TEE by separating the execution domains and creating a sandboxed environment to execute non-secure applications.

In real-life scenarios, this gives flexibility to the deployment of applications from different providers, with distinct levels of trust regarding accessing features and resources on a system.

In this last chapter, we have analyzed the mechanisms available in the TrustZone-M technology. TrustZone-M can be activated on ARMv8-M systems for the purpose of integrating a powerful, hardware-assisted solution, aimed to protect system components from any access that has not been explicitly authorized by a system supervisor component running in the secure domain.
