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.

This chapter has given us the necessary information to start programming system support for the most popular local bus communication interfaces available on embedded targets. Accessing peripherals and other microcontrollers in the same geographical location is one of the typical requirements of embedded systems interacting with sensors, actuators, and other devices in proximity of the embedded system.

Several implementations providing a higher level of abstraction to the transceivers analyzed here already exist. The serial communication protocols covered in this chapter, namely UART, SPI, and I2C, are usually accessible through drivers that are part of the board support kit and do not need to be reimplemented from scratch. This chapter, however, purposely focused on studying the behavior of the components from the closest possible point of view, to better understand the interface provided by the hardware manufacturer, and possibly provide the tools to design new ways of...
