For my loving girlfriend, Anne-Laure, who put up
with entire weekends spent on my PC (while she spent
her weekend on her laptop, sending me encouraging
electronic messages). Thank you for supporting me
when I should have been paying attention to you.
For my wonderful daughter, Eléna. Thank you for
letting daddy work when I really should have spent
more time playing with you, and despite what I might
have said at the time, thank you for unplugging my
computer when I ignored you for too long. Your smiles
and fi rst words are what powered me through the late
nights and tight deadlines.
ABOUT THE AUTHOR
JAMES A. LANGBRIDGE does not like talking about himself in the third person, but he will try
anyway. James was born in Singapore, and followed his parents to several countries before settling
down in Nantes, France, where he lives with his partner and their daughter.
James is an embedded systems consultant and has worked for more than 15 years on industrial,
military, mobile telephony, and aviation security systems. He works primarily on low-level
development, creating bootloaders or optimizing routines in assembly, making the most of small
processors. When not on contract, James trains engineers on embedded systems, or he makes new
gizmos, much to the dismay of his partner.
James wrote his fi rst computer program at age six and has never stopped tinkering since. He began
using Apple IIs, ZX80s and ZX81s, before moving on to BBC Micros and the Amiga, before fi nally
having no other option but to use PCs.
ABOUT THE TECHNICAL EDITORS
CHRIS SHORE is the Training and Education Manager at ARM Ltd, based in Cambridge, UK. He
has been responsible for training ARM’s global customer base for over 13 years, delivering nearly
200 training courses per year on everything from chip design to software optimization. Chris has
taught classes on every continent except Antarctica — opportunities there are limited, but surely it’s
only a matter of time! He is a regular speaker at industry conferences.
Following graduation with his degree in Computer Science from Cambridge University, Chris worked
as a software consultant for over 15 years, primarily in embedded real-time systems, before moving
to ARM in 1999. He is a Chartered Engineer and Member of the Institute of Engineering and
Technology, and he sits on the Industry Advisory Board of Queen Mary College, London. In his free
time he keeps bees, tries to play the guitar, and is always looking for ways to visit new countries.
JEAN-MICHEL HAUTBOIS lives in France and has been developing software professionally, or as
a hobbyist, for more than 15 years. He is currently employed as an embedded Linux consultant
with Vodalys, and is the architect of his company’s main video product which was developed on
an ARM-based SoC. He is involved in the decision-making process when a new hardware product
needs to be created and performance is critical. In his free time Jean-Michel likes to travel, and he
enjoys spending time with his wife and newborn son.
