Computers as Components: Principles of Embedded Computing System Design [Paperback]

Book Description

ISBN-10: 0123694590 | ISBN-13: 978-0123694591 | Publication Date: July 15, 2005 | Edition: 1

The vast majority of existing computers are embedded in the myriad of intelligent devices and applications-not in desktop machines. We are witnessing the emergence of a new discipline with its own principles, constraints, and design processes.

Computers as Components is the first book to teach this new discipline. It unravels the complexity of these systems and the tools and methods necessary for designing them. Researchers, students, and savvy professionals, schooled in hardware or software, will value the integrated engineering design approach to this fast emerging field.

* Demonstrates concepts and techniques using two powerful real-world processors as case studies throughout the book: the ARM processor and the SHARC DSP (digital signal processor).
* Illustrates the major concepts of each chapter with real-world design examples such as software modems, telephone answering machines, and video accelerators.
* Teaches the basics of UML (Unified Modeling Language) and applies it throughout the text to help you visualize stages in the design process.
* Illustrates real-time operating systems using the POSIX real-time extensions and Linux.
* Describes performance analysis and optimization of embedded software, including the effects of caches.

Editorial Reviews

Review

"This book will prove invaluable as a means for acquiring knowledge in this important and newly emerging field. It will also serve as a reference in actual design practice and be a trusted companion in the design adventures ahead."
-From the foreword by Lynn Conway, Professor Emerita, Department of Electrical Engineering and Computer Science, University of Michigan, USA

"This book is the first to bring embedded systems technology and techniques together under a single cover. The author provides a practical overview of the many interrelated issues that must be addressed during the complete design cycle of an embedded computer system."
-Randolph E. Harr, Director of Research, Advanced Technology Group (ATG), Synopsys, Inc., USA

1.0 out of 5 stars Not Recommended, January 17, 2009

By 

Software Engineer - See all my reviews

This review is from: Computers as Components, Second Edition: Principles of Embedded Computing System Design (The Morgan Kaufmann Series in Computer Architecture and Design) (Paperback)

This book was the required text for a class or I would not have purchased it. It is poorly organized and poorly written. The author provides an annoying amount of superfluous commentary and makes unnecessary digressions, both of which obscure the points he must be trying to make, and the content is sometimes repetitious. Finally, the book contains grammatical errors and the text includes what must surely be editorial content such as "stet" and "the acronym is the name", rendering some sentences unintelligible. Most books have their faults, but this one has too many to make it a worthwhile purchase; there are better texts which cover the same material.

4.0 out of 5 stars Good intro to embedded development, January 28, 2006

This review is from: Computers as Components: Principles of Embedded Computing System Design (Paperback)

Do you know what percentage of all computers run Windows or some kind of Unix? Guess. I'll give you the answer later.

This book is about all the other computers out there - the ones in your car's airbags and antilock brakes; in your watch, cellphone, TV and its remote, CD player, and computer keyboard; in your implanted defibrillator.

Wolf starts with an introduction in terms of a personal-scale, practical example. Next he goes into what a CPU is in lots more detail than most programmers ever think about - the kind of detail you need when the CPU interacts so intimately with the other components in the system. Maybe you never heard of the ARM or SHARC processors (unless you already do embedded work), but they're good representative choices. ARM is an incredibly common core architecture, with supervisor mode and memory mapping, what it takes to run a "real" OS, whether it does or not. SHARC is a signal processor - a real processor, but with extras for fast artihmetic processing. Together, the two stand adequately for a large fraction of the embedded processors in use.The next chapter goes over hardware basics: the bus, memory mapped IO, interface issues, and in-circuit debugging.

The rest of the book generally covers higher level issues: software design, embedded and real-time OSs, coprocessors, and networks. Although coverage of IIC and similar board-level communication is good, I found the ethernet discussion weak. Anyone working at this level is likely to need 802.2 protocols, which I did not see mentioned. The book's strengths far outnumber its occasional soft spots, though.

Embedded computing is a huge, many faceted field, so no book can cover more than a tiny fraction of what it means. Still, this addresses a broad, useful range what you need to program 99% of the computers out there - because only about 1% run Windows or Unix.

4.0 out of 5 stars explains hierarchy of design, from devices to operating system, January 26, 2007

This review is from: Computers as Components: Principles of Embedded Computing System Design (Paperback)

The average person in the US now uses a computer. Typically running a Microsoft operating system or unix or linux. Yet there is an entire ecosystem of embedded computers out there, invisible to most people. Wolf's text explains how you can program such computers as well as design the circuitry in which they might exist. Here, "computer" in the book essentially means microprocessor plus some off-chip memory. The book surveys two main microprocessor families - ARM and SHARC. These are not the most common microprocessors. (Which might be by Motorola.). But Wolf chooses them to illustrate different design ideals for their instruction sets.

One nice thing about the book is that you get a direct grasp of the hierarchy of design and logic. Climbing from the low level devices of latches, gates, flip-flops and the like, to the microprocessor and its machine language, to the corresponding and far easier to use assembly language. Then, upwards to an operating system.
