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.

Application protocols

In order to be able to communicate with remote devices and cloud servers in a distributed scenario, embedded systems must implement standard protocols that are compatible with the existing infrastructure. Two of the most common approaches taken when designing remote services are as follows:

  • Web-based services
  • Message protocols

The former is mainly the classic, client-server, Representational State Transfer (REST)-based communication that is popular in web services accessed through personal computers or portable devices. Web services require no adaptation in particular on the cloud side to support embedded systems, except for the choice of an embedded-friendly cipher set, as described in the Securing socket communication section. However, the request-reply communication model introduces some restrictions on the design of distributed applications. The HTTP protocol can be upgraded by common agreement on the two HTTP endpoints, and support WebSocket...
