system architecture

I like this book because it talks briefly about different MICs and interfaces. I gained enough knowledge to build my own embedded computer. I would like to see more books from same author.

This book is great for beginners. It is very informative and easy to read. I like the way the author describes timing diagrams seen in many microcontroller datasheets. I am impressed with his love for the ATMEL AVR microcontroller.
I used this book for a small PIC project.

Some of the O'Reily books really shine and this is one of them. I'm an experienced hardware engineer, but I still got some good tidbits out of this book which is all the more impressive when you consider it's written for a relative beginner. The author does a nice job with both the content and writing style.

It covers many topics which are relatively common knowledge among experienced hardware designers but you rarely find in one book. Some of those topics I've never seen in ANY book. There's some good stuff here. That said, it's probably not the ideal book for someone who's already tackled a few successful embedded hardware designs.
