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.

Sandboxing

Sandboxing is a generic concept in computer security that refers to a set of hardware and software measures that limit the “view” of the system for one or more of its components, to restrict the area of the system affected by accidental malfunctions or purposedly forged malicious attacks and prevent them from spreading across the entire system. Sandboxing can have different forms and implementations, which may or may not leverage specific hardware functionalities to improve safety and effectiveness.

By the term TEE, we refer to those sandbox mechanisms that involve the CPU keeping track of the secure status of the running code at all times, without significantly impacting the performance of the running application. Due to these TEE mechanisms being intrinsically bonded to the CPU design, TEE behavior, management, and communication models in sandboxes differ across heterogeneous platforms and heavily depend on the architecture. Moreover, TEEs can be used...
