A number of people have assisted me in researching for and writing this book.

First of all, a big thank you to my colleagues in ARM for their help in reviewing and suggesting improvements, especially Edmund Player, Nick Sampays, and Dominic Pajak, and also Drew Barbier, Colin Jones, Simon Craske, Jon Marsh, and Robert Boys.

I would also like to thank a number of external reviewers whose input in terms of feedback has enabled me to hone and improve the quality of the book's technical information. They are Joe Yu and Kenneth Dwyer from NXP, John Davies from Glasgow University, and Jeffrey S. Mueller from Triad Semiconductor. In addition to those who reviewed the prepublication book, I would also thank the following who assisted me while I was writing it by answering my technical inquiries and by providing product information. They are Kenneth Dwyer, David Donley, and Amit Bhojraj from NXP; Drew Barbier from ARM; Milorad Cvjetkovic from Keil; Jeffrey S. Mueller, William Farlow, and Jim Kemerling from Triad Semiconductor; Jamie Brettle from National Instruments; Derek Morris from Code Red Technologies; Brian Barrera from CodeSourcery; and the sales teams from Rowley Associates, Steinert Technologies, IAR Systems, and TASKING.

I would also thank the staff from Elsevier for their professional work in getting this book published.

And finally, a big thank you to all my friends within and outside of my work environment whose unstinting encouragement enthused and enabled me (though the odd cup of coffee helped too) to start and then complete the book.
