Embedded Systems Architecture

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.

Summary


This chapter has given us the necessary information to start programming system support for the most popular local-bus communication interfaces available on embedded targets. Accessing peripherals and other microcontrollers in the same geographical location is one of the typical requirements of embedded systems interacting with sensors, actuators, and other devices in proximity of the target.

There already exist several implementations providing a higher level of abstraction to the transceivers analyzed here. This chapter, however, purposely focused on studying the behavior of the components from the closest possible point of view, to better understand the interface provided by the hardware manufacturer, and possibly provide the tools to design new ways of accessing the interfaces, tailored or optimized for a specific platform or scenario, while also understanding the choices behind some of the the protocol design characteristics.

In the next chapter, we'll provide a description of...
