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.

Power Management and Energy Saving

Energy efficiency has always been one of the leading factors in the microcontroller market. Since the early 2000s, signal-processing 16-bit RISC microcontrollers, such as the MSP430, have been designed for extremely low-power usage and are still leading the path of ultra-low-power optimization architectures in embedded systems.

In the last few years, more advanced 32-bit RISC microcontrollers, rich in features and capable of running real-time operating systems, have scaled down in size and power consumption, and set foot in the low-power and ultra-low-power domains. Battery-powered systems and devices relying on energy-harvesting techniques are becoming more and more common in many industries. Low-power wireless communication is now offered by a number of connected platforms, so an increasing number of IoT systems include low-power and ultra-low-power characteristics in their design.

Depending on the architecture, microcontrollers offer different...
