This textbook provides a clear and concise introduction to computer architecture and implementation. Two important themes are interwoven throughout the book. The first is an overview of the major concepts and design philosophies of computer architecture and organization. The second is the early introduction and use of analytic modeling of computer performance. The author begins by describing the classic von Neumann architecture, and then presents in detail a number of performance models and evaluation techniques. He goes on to cover user instruction set design, including RISC architecture. A unique feature of the book is its memory-centric approach - memory systems are discussed before processor implementations. The author also deals with pipelined processors, input/output techniques, queuing modes, and extended instruction set architectures. Each topic is illustrated with reference to actual IBM and Intel architectures. The book contains many worked examples and over 130 homework exercises. It is an ideal textbook for a one-semester undergraduate course in computer architecture and implementation. • Concise yet detailed introduction to the essentials of computer architecture • Illustrates key points with reference to real IBM and Intel computer systems • Author is a member of the US National Academy of Engineering and a Fellow of the IEEE • Includes unique coverage of Intel MMX technology
