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.

Local Bus Interfaces

The communication between an embedded system and other systems in its vicinity is enabled by a few protocols. Most microcontrollers designed for embedded systems support the most common interfaces that control and discipline the access to serial lines. Some of these protocols are so popular that they have become the standard for wired inter-chip communication among microcontrollers, and for controlling electronic devices, such as sensors, actuators, displays, wireless transceivers, and many other peripherals. This chapter describes how these protocols work, specifically focusing on the implementation of the system software, through examples running on the reference platform. In particular, we will cover the following topics in this chapter:

  • Introducing serial communication
  • A UART-based asynchronous serial bus
  • An SPI bus
  • An I2C bus

By the end of this chapter, you will learn how to integrate the common serial communication protocols.
