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.

Validation


Debugging alone, or even simple output analysis, is often not enough when verifying system behavior and identifying issues and unwanted effects in the code. Different approaches may be taken to validate the implementation of the single components, as well as the behavior of the entire system under different conditions. While, in some cases, the results can be directly measurable from the host machine, in more specific contexts, it is often difficult to reproduce the exact scenario, or to acquire the necessary information from the system output.

External tools may come in handy, especially in the analysis of communication interfaces and network devices in a more complex, distributed system. In other cases, single modules can be tested off-target using simulated or emulated environments to run smaller portions of the code base.

Different tests, validation strategies, and tools are considered in this section, to provide solutions for any scenario.
