Embedded Systems Architecture

By: Daniele Lacamera

Overview of this book

Embedded systems are self-contained devices with a dedicated purpose. We come across a variety of fields of applications for embedded systems in industries such as automotive, telecommunications, healthcare and consumer electronics, just to name a few. 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. You will first be guided to set up an optimal development environment, then move on to software tools and methodologies to improve the work flow. You will explore the boot-up mechanisms and the memory management strategies typical of a real-time embedded system. Through the analysis of the programming interface of the reference microcontroller, you'll look at the implementation of the features and the device drivers. Next, you'll learn about the techniques used to reduce power consumption. Then you will be introduced to the technologies, protocols and security aspects related to integrating the system into IoT solutions. By the end of the book, you will have explored various aspects of embedded architecture, including task synchronization in a multi-threading environment, and the safety models adopted by modern real-time operating systems.

The GCC toolchain

An embedded toolchain is a set of software tools aimed to build software for a specific platform. While, in some cases, the complexity of the toolchain can be abstracted through a GUI, it is often distributed as a set of standalone applications, each one serving a specific purpose. Understanding the single tools and learning how to use them properly speeds up the development process and gives us a closer look at how things work under the hood.

GCC is nowadays one of the reference toolchains to build embedded systems, due to its modular structure allowing backends for multiple architectures. Thanks to its open source model, and the flexibility in building tailored toolchains from it, GCC-based toolchains are among the most popular development tools in embedded systems.

Building software using a command-line-based toolchain has several advantages, including the possibility of automating the intermediate steps that would build all the modules up from the source code into the...
