The PowerPC Architecture

I read the review from the other reader and I want to give justice to this book. If the person who bought this book is disappointed because s/he was hoping to get something else instead, it has nothing to do with the quality of the current material. A lot of not so positive reviews I read here fall in the same "erroneously bought" critic syndrom. Regarding this book, this is really excellent if you want to go deeper than simply reading the manufacturer's user and programming manuals. I work daily on PowerPC computers implementing low level OS routines and this book does a great job at helping me on using specific instructions. In fact, this material added to the (free) manufacturer manuals and Gary Kacmarcik's book is all one need to work intimately on this wonderful CPU. If you need something at a more generic level, buy J. Hennessey's book.
