A Must for Beginners, and Worth It For Hot Shots Too

By Scott L. Davis - October 24, 2003

When I first started reading this work, it seemed decidedly to be for beginners only. I was pleasantly surprised however, how many new concepts and ideas I learned by the time I completed it. I found the "points to remember" and Chapters 11, 13-16 to be particularly useful because they highlight the pitfalls that I've seen even the most seasoned RTOSers fall into. I ended up buying the book for all my firmware developers and made the above mentioned sections mandatory reading for them. Although I have read several books on real time this is definitely the most complete because it references the real time concepts in the context of a real live OS - VxWorx. The information is presented in such a way that it can easily be applied to any RTOS such as QNX, InTime, MsCE, and MuOS. All my firmware new hires are given this book on the first day of work, and they can't start coding until they've finished it.

Good VxWorks-centric Intro to Real Time OS

By calvinnme - December 5, 2005

This book is a good introduction to readers who are beginners in the world of embedded programming and real-time operating systems. A real-time OS facilitates the creation of real-time systems, but does not guarantee that they are real-time. Nor does an RTOS necessarily have high throughput. Instead, they enable, through specialized scheduling algorithms and deterministic behavior, the guarantee that system deadlines can be met. Thus a real-time OS is valued more for how quickly it can respond to an event than for the total amount of work it can do.
This book, written by a senior architect at Wind River Systems, is very VxWorks centric. This is OK, since VxWorks is one of the better commercial real-time operating systems out there, having been on the scene in various forms since 1983. This book will introduce you to all of the terminology you will need to be familiar with before you write code that uses VxWorks. I highly recommend it for anybody who is or is planning to get... read more

A Really Good Explanation of Real Time Issues

By Arnie Berger - July 11, 2003

"Real-Time Concepts" is a book that tackles one of the most difficult subject areas of embedded systems programming. Bugs that are introduced because of problems with the behavior of a real-time system can be extremely subtle and difficult to correct. These bugs can also have disasterous effects. Even Computer Science students who take an Operating Systems class probably never deal with a Real Time Operating System. In this book, the authors attempt to explain the concepts of real time programming. In my opinion, they generally succeed at their task. They keep the code examples to a bare minimum, which I think is a good strategy, because code examples can often obscure a concept, rather than explain it. If the book has a weakness, I think that it is the introductory sections. The first 50 pages or so cover no new ground and have been covered much more extensively by other authors in the CMP Books series. However, the book really hits its stride at Chapter 4,... read more
