Embedded Software
This is an awesome book for anyone who is new to embedded software development. I used it while taking a class at UCIrvine and it was an interesting book and not hard to read, very reader friendly. Definetly a good book for anyone starting a career in embedded software development.

Excellent intro to the fundamentals
Many people would argue that the material in this text is far too basic. I think this is precisely the strength of this book. I enjoyed reading this book despite being an experienced embedded developer.

There is no one-stop-shop in embedded software development. If you adopt it as a career, there are many things you will need to learn over time: architectures of multiple processors, a variety development tools, RTOSes and a lot more. For the most part the book stays clear of the specifics of all of these. However, it does teach you the fundamentals of all of them. The information about hardware interfacing, processors, interrupts, shared data problems, RTOS based design, and common mistakes is sufficient to get a new-comer started quickly. In my early days, I spent hours, sometimes days, chasing bugs similar to those this book teaches you to avoid.

In short, the book is just what says it is: "What you need to know to get started with embedded systems development". I would highly recommend it to any newcomer to this field.

Dated, but still valuable
This book hits most of the major points in embedded software programming, clearly and concisely. It it almost 10 years old, though, and some of the discussion shows it (especially hardware). It would be great if they would do a second edition, as the book is a great read otherwise.

microC/OS is a good example of small operating system.
I think microC/OS is a good example of small operating systems such as TOPPERS/ssp(smallest set profile). This book describe Hardware fundamentals for the software engineer (chapter 1) for examples VCC(Voltage Connected to Collector), And gates and Or gates and D Flip Flops.
Advanced Hardware Fundamentals(chapter 2) describe Busses, DMA(Direct Memory Access), and Interrupts(also in chapter 4).
Survey of software architecutres(chapter 5) is important articles.
Introduction to real-time operating systems(chapter 6) include semaphores that is traditional technology.
All of the contents are good for primer. In the CD-ROM there are answer of the problems(exercise or practice) and additional programs.
ps.
microC/OS is made by Jean J. Labrosse.
He make a new book, microC/OS-II.

A very good book for starters in embedded system
I've done quite some application software design. But I'm totally new to embedded software design. I found this book is very useful for me. The whole book is very clear and illustrative. It provides many useful points in designing embedded software that my be overlooked by application software engineer like me.
