Title: Computer Architecture: A Quantitative Approach
Publisher: Morgan Kaufmann
Authors: John L. Hennessy, David A. Patterson, David Goldberg
Rating: 5/5
Customer opinion - 5 stars out of 5
An excellent book, now updated


First, this is certainly not an introductory text on Computer Architectures. The authors assume that people reading it have already had an introductory class or some experience. Simply put, the book is not intended to explain how cache memory works, but to present a thourough quantitative analysis to show why and when one implementation works better than another, and what improvements have been devised recently to speed this or this other measurement.Of course, the best choice for this book would be to have it preceeded by "Computer Organization: the HW/SW interface" (aka CO-HSI), by the same authors, since it would help to better comprehend the MIPS64 and the low-level design behind it, since CO-HSI develop an older version of the MIPS itself.
This is for sure one of the most informative books I've ever encountered both as a student and as a SW engineer. It contains an overwhelming quantity of data, tips, warnings, tecniques so that the over 1100 pages seem incredibly dense. And don't be fooled the book is "only so little": there are other seven online appendixes that can be downloaded, that will add up to more than 250 pages to the book.As experience teaches, however, quantity does not always mean quality. Yet, it seems this doesn't apply to this book, because the quality of its content is highly informative and interesting for those involved with true CA designs.
Since the first chapter it's clear that target of the book is not a survery of CAs, but a guide through the bunch of considerations and problems a design of a new CA must cope with today. I mean today because much of the data collected and presented is binded to (and updated to) the current edition and its realease date. So covered CAs for this 3ed will feature IA-64 or Sony Playstation II among the others. Nonetheless, it would be misleading to think that next year the book will become useless. Most of the considerations the authors develop and present are quite long lasting (the usage patterns of ISAs, e.g., have incurred little change since the second edition, six years ago).
This edition presents noticeable changes, even if there's no doubt the core is that of CA-AQA 2ed. To mention a few, the first chapter is of course almost totally new since it's the most time-bounded of the book. The elder chapter four (Advanced Pipelining and Instruction Level Parallellism) has been expanded into two chapters, one dealing with Hardware approaches and one with Software approaches (and both with hybrid ones). This goes into great benefit for the reader since it seems we never get enough details on modern CAs and their complexity otherwise.However, changes has been done even in the way of reductions, and that's especially true for the elder chapter three (Pipelining). It was a full 100 pages chapter, featuring an astonishing treatment of the topic, that has been fundamental in my class of CA II. In the 3ed edition, this chapter has been moved to a shorter appendix at the end, and I think this appendix can't compare with its predecessor (even if some of the "cut" topics have been then spread through chapters 3-4 in the 3ed).
About the exposition of the topics, the authors have built a solid way to make things clear for students and not, beginners and not on quantitative analysis. The book is full of figures, graph, citation and feature a wide bibliography at the end of the book and a reasoned set of references at the end of each chapter.
The only difficulties reading this book will arise only because of the complexity of the topics, who themselves require a fair amount of attention, not because of the language which keeps always clear and straightforward.
This said, I think the book is a fully deserved 5 stars one, with no concurrents on its kind, scope and utility. That's probabily why it has been worlwide used since its first edition.

Title: Programming Perl (3rd Edition)

Starters should look for something else, and ...


I have both v.4 and v.5 of this Camel book, and have been using it from time to time. I know it's written by the creator of Perl. Yet I feel like saying the following: It looks to me that this book has tried to be an introduction to and reference of Perl at the same time, yet somehow IMNSHO it is not particularly successful in either ways. I do thank Mr.Wall for creating Perl, though.

Step-by-Step and Easy to Follow


For a few years now, I have wanted to learn how to program in JAVA. I bought books on JAVA but always hit road blocks along the way (because the author assumed I already knew something) that unmotivated me. In Java 2 for Dummies, Barry Burd has written a step-by-step book that could teach a near computer illiterate how to program in JAVA. He even includes directions to setting up the computer for convenience while programming. Explanations make the reader feel as though s/he is in a conversation with the author himself. I did not imagine that learning a programming language could be so easy.
