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 an overview of the design of machine-to-machine distributed systems and IoT services including connected embedded devices, with a focus on security elements that are too often overlooked or underestimated in embedded development. The technology proposed allows full, professional-grade, secure, and fast TCP/IP connectivity on very small targets, and uses state-of-the-art technology, such as the most recent version of the TLS cipher suites. Multiple approaches have been considered for a broader view on the technologies, protocols, and security algorithms available for building distributed embedded systems.

The next chapter will illustrate the multitasking possibilities of modern embedded microcontrollers, by explaining how to write a small scheduler for Cortex-M microprocessors from scratch, and will summarize the key roles of a real-time operating system running on an embedded target.
