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.

Embedded operating systems

As illustrated in the previous sections of this chapter, building a scheduler tailored to a custom solution from scratch is not impossible and, if done properly, would provide the closest approximation of the desired architecture and focus on the specific characteristics offered by the target hardware. In a real-life scenario, however, it is advisable to consider one of the many embedded operating systems options available and ready to be integrated into the architecture among those supporting the selected hardware platform, and providing the features that we have learned about in this chapter.

Many of the available kernel implementations for microcontrollers are open source and in a healthy development state, so they are deserving of their well-established role in the embedded market. A few of them are sufficiently popular and widely tested to provide a foundation for building reliable embedded multitasking applications.
