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.

Debugging alone, or even simple output analysis is often not enough when verifying system behavior and identifying issues and unwanted effects in the code. Different approaches may be taken to validate the implementation of single components, as well as the behavior of the entire system under different conditions. While, in some cases, the results can be directly measurable from the host machine, in more specific contexts, it is often difficult to reproduce the exact scenario or to acquire the necessary information from the system output.

External tools may come in handy, especially in the analysis of communication interfaces and network devices in a more complex, distributed system. In other cases, single modules can be tested off-target using simulated or emulated environments to run smaller portions of the code base.

Different tests, validation strategies, and tools are considered in this section to provide solutions for any scenario.
