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.

Network interfaces

Embedded devices often integrate one or more communication interfaces. Many microcontrollers integrate the Media Access Control (MAC) portion of an Ethernet interface, so connecting a Physical Layer Transceiver (PHY) would enable LAN access. Some devices are coupled with radio transceivers, operating at fixed frequency ranges and implementing one or more protocols to communicate over wireless links. Frequently used frequencies for wireless communication are the 2.4 GHz band, in use by Bluetooth and 802.11 Wi-Fi, and some specific ISM ranges of frequency below 1 GHz, which depend on local regulations. Usable sub-GHz frequencies include the 868 MHz ISM band in the European Union and the 915 MHz ISM band in the US. Transceivers are usually designed to access the physical layer according to specific link protocols, regulating shared access to the physical media among two or more devices. While two interfaces accessing the same media can have different configurations...
