Wikibooks:Collections Preface
This book was created by volunteers at Wikibooks ( http:/ / en. wikibooks. org).
What is Wikibooks?
Started in 2003 as an offshoot of the popular Wikipedia project, Wikibooks is
a free, collaborative wiki website dedicated to creating high-quality textbooks
and other educational books for students around the world. In addition to
English, Wikibooks is available in over 130 languages, a complete listing of
which can be found at http:/ / www. wikibooks. org. Wikibooks is a "wiki",
which means anybody can edit the content there at any time. If you find an
error or omission in this book, you can log on to Wikibooks to make
corrections and additions as necessary. All of your changes go live on the
website immediately, so your effort can be enjoyed and utilized by other
readers and editors without delay.
Books at Wikibooks are written by volunteers, and can be accessed and printed for free from the website. Wikibooks
is operated entirely by donations, and a certain portion of proceeds from sales is returned to the Wikimedia
Foundation to help keep Wikibooks running smoothly. Because of the low overhead, we are able to produce and sell
books for much cheaper then proprietary textbook publishers can. This book can be edited by anybody at any
time, including you. We don't make you wait two years to get a new edition, and we don't stop selling old versions
when a new one comes out.
What is this book?
This book was generated by the volunteers at Wikibooks, a team of people from around the world with varying
backgrounds. The people who wrote this book may not be experts in the field. Some may not even have a passing
familiarity with it. The result of this is that some information in this book may be incorrect, out of place, or
misleading. For this reason, you should never rely on a community-edited Wikibook when dealing in matters of
medical, legal, financial, or other importance. Please see our disclaimer for more details on this.
Despite the warning of the last paragraph, however, books at Wikibooks are continuously edited and improved. If
errors are found they can be corrected immediately. If you find a problem in one of our books, we ask that you be
bold in fixing it. You don't need anybody's permission to help or to make our books better.
Wikibooks runs off the assumption that many eyes can find many errors, and many able hands can fix them. Over
time, with enough community involvement, the books at Wikibooks will become very high-quality indeed. You are
invited to participate at Wikibooks to help make our books better . As you find problems in your book don't just
complain about them: Log on and fix them! This is a kind of proactive and interactive reading experience that you
probably aren't familiar with yet, so log on to http:/ / en. wikibooks. org and take a look around at all the
possibilities. We promise that we won't bite!
Who are the authors?
The volunteers at Wikibooks come from around the world and have a wide range of educational and professional
backgrounds. They come to Wikibooks for different reasons, and perform different tasks. Some Wikibookians are
prolific authors, some are perceptive editors, some fancy illustrators, others diligent organizers. Some Wikibookians
find and remove spam, vandalism, and other nonsense as it appears. Most wikibookians perform a combination of
these jobs.

It's difficult to say who are the authors for any particular book, because so many hands have touched it and so many
changes have been made over time. It's not unheard of for a book to have been edited thousands of times by
hundreds of authors and editors. You could be one of them too , if you're interested in helping out. At the time this
book was prepared for print, there have been over ' edits made by over 0 ' registered users. These numbers are
growing every day.
Wikibooks in Class
Books at Wikibooks are free, and with the proper editing and preparation they can be used as cost-effective
textbooks in the classroom or for independent learners. In addition to using a Wikibook as a traditional read-only
learning aide, it can also become an interactive class project. Several classes have come to Wikibooks to write new
books and improve old books as part of their normal course work. In some cases, the books written by students one
year are used to teach students in the same class next year. Books written can also be used in classes around the
world by students who might not be able to afford traditional textbooks.
Happy Reading!
We at Wikibooks have put a lot of effort into these books, and we hope that you enjoy reading and learning from
them. We want you to keep in mind that what you are holding is not a finished product but instead a work in
progress. These books are never "finished" in the traditional sense, but they are ever-changing and evolving to meet
the needs of readers and learners everywhere. Despite this constant change, we feel our books can be reliable and
high-quality learning tools at a great price, and we hope you agree. Never hesitate to stop in at Wikibooks and make
some edits of your own. We hope to see you there one day. Happy reading!
Embedded Systems/Embedded Systems
Introduction
Embedded Technology is now in its prime and the wealth of knowledge available is mindblowing. However, most
embedded systems engineers have a common complaint. There are no comprehensive resources available over the
internet which deal with the various design and implementation issues of this technology. Intellectual property
regulations of many corporations are partly to blame for this and also the tendency to keep technical know-how
within a restricted group of researchers.
Before embarking on the rest of this book, it is important first to cover exactly what embedded systems are, and how
they are used. This wikibook will attempt to cover a large number of topics, some of which apply only to embedded
systems, but some of which will apply to nearly all computers (embedded or otherwise). As such, there is a chance
that some of the material from this book will overlap with material from other wikibooks that are focused on topics
such as low-level computing, assembly language, computer architecture, etc. But we will first start with the basics,
and attempt to answer some questions before the book actually begins.
What is an Embedded Computer?
The first question that needs to be asked, is "What exactly is an embedded computer?" To be fair, however, it is
much easier to answer the question of what an embedded computer is not, than to try and describe all the many
things that an embedded computer can be. An embedded computer is frequently a computer that is implemented for a
particular purpose. In contrast, an average PC computer usually serves a number of purposes: checking email,
surfing the internet, listening to music, word processing, etc... However, embedded systems usually only have a
single task, or a very small number of related tasks that they are programmed to perform.
