Overview of this book

Developing applications for embedded systems may seem like a daunting task as developers face challenges related to limited memory, high power consumption, and maintaining real-time responses. This book is a collection of practical examples to explain how to develop applications for embedded boards and overcome the challenges that you may encounter while developing. The book will start with an introduction to embedded systems and how to set up the development environment. By teaching you to build your first embedded application, the book will help you progress from the basics to more complex concepts, such as debugging, logging, and profiling. Moving ahead, you will learn how to use specialized memory and custom allocators. From here, you will delve into recipes that will teach you how to work with the C++ memory model, atomic variables, and synchronization. The book will then take you through recipes on inter-process communication, data serialization, and timers. Finally, you will cover topics such as error handling and guidelines for real-time systems and safety-critical systems. By the end of this book, you will have become proficient in building robust and secure embedded applications with C++.

Exploring object pools

As we discussed in the first recipe in this chapter, preallocation of all memory used by the application is an efficient strategy that helps embedded applications avoid various pitfalls related to memory fragmentation and allocation time.

One disadvantage of ad-hoc memory preallocation is that the application is now responsible for the tracking of preallocated object usage.

Object pools aim to hide the burden of object tracking by providing a generalized and convenient interface, similar to dynamic memory allocation but working with objects in the preallocated arrays.

How to do it...

In this recipe, we will create a simple implementation of an object pool and learn how to use it in your applications...
