I seldom write reviews. This book changed my life, and I've been developing embedded software for twenty-five years. Samek's nested finite state machines, which he calls Hierarchical State Machines (HSMs) give the embedded software architect a framework arguably as fundamental as an RTOS. If you are creating event-driven embedded software where objects have member variables representing their state at any given time, this book is required reading."

PSICC is a revolutionary title that will transform the way you design and implement embedded code. Kiss goodbye to spaghetti mess and say hello to efficient, well structured, scalable designs. The book essentially gives you too things, an overview of embedded system concepts and pitfalls, along with the full framework code to implement sophisticated designs in UML format. The C/C++ framework presented here offers, in my opinion, a superior alternative to any commercially available UML CASE tool solution."

The knowledge on statechart that I learn from this book greatly tidy up my code, even I have only finished reading a few chapters. The concept is well-explained with the aid of chart diagram and codes. Furthermore, this books is platform independent, you can use it on any microcontroller. I highly recommend this book to intermediate and advanced embedded programmer!"

This book was a definite eye-opener for me with regard to state machines. I recently rewrote a major piece of code to utilize the Quantum Framework (included with the book) and it has worked wonders. My previous code used a more traditional state machine and had quickly evolved into spaghetti code. The hierarchical state machine approach made the new code smaller, more robust, and much easier to maintain and extend."

As the title indicates, this book brings the topic of statecharts from the realm of expensive design tools to the PRACTICAL realm, illustrating its points with full examples and extensive commentary."

The book is well structured. The UML Statecharts are well introduced. The Actives Objects approach and the related Framework are very attractive. With the Framework (QF) for embedded real-time systems included, you are really able to use it for your application. You can then focus on your application objects and no more on the "glue" around them. You have a common strategy for all your applications. The best book on UML for embedded system from a long time.

This book has done a great job in consolidating many key concepts and techniques in embedded software design... the author proposed a truly reusable and integrated framework which is very well designed and particularly suitable for resource constrained embedded systems. Author's implementation of state machines is innovative and remarkable. It supports state nesting, automatic execution of entry/exit actions and default event handling by superstates. This allows you to implement UML statecharts in C or in C++ conveniently."
