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.

Memory Management

Handling memory is one of the most important tasks for an embedded system programmer, and surely the most important to take into account in every phase of the development of a system. This chapter is about the models commonly used to manage memory in an embedded system, the geometry and the mapping of the memory, and how to prevent issues that could compromise the stability and safety of the software running on the target.

This chapter is divided into four parts:

  • Memory mapping
  • The execution stack
  • Heap management
  • The memory protection unit

By the end of this chapter, you will have an in-depth knowledge of how to manage the memory in an embedded system.
