The performance of software systems is dramatically affected by how well software designers understand the basic hardware technologies at work in a system. Similarly, hardware designers must understand the far reaching effects their design decisions have on software applications. For readers in either category, this classic introduction to the field provides a deep look into the computer. It demonstrates the relationship between the software and hardware and focuses on the foundational concepts that are the basis for current computer design. Using a distinctive "learning by evolution" approach the authors present each idea from its first principles, guiding readers through a series of worked examples that incrementally add more complex instructions until they have acquired an understanding of the entire MIPS instruction set and the fundamentals of assembly language. Computer arithmetic, pipelining, and memory hierarchies are treated to the same evolutionary approach with worked examples and incremental drawings supporting each new level of sophistication. The design, performance, and significance of I/O systems is also discussed in depth, and an entire chapter is devoted to the emerging architectures of multiprocessor systems. * Real Stuff provides relevant, tangible examples of how the concepts from the chapter are implemented in commercially successful products. * Fallacies and Pitfalls share the hard-won lessons of the authors and other designers in industry. * Big Pictures allow the reader to keep major insights in focus while studying the details. * Key terms, all fully defined in an end-of-book glossary, summarize the essential ideas introduced inthe chapter. The prior edition of this text is a computer science classic, and now has been updated to reflect the rapid evolution of software and hardware trends, concepts, issues and technologies. Although this is an undergraduate CS text, it's not an introductory one. It lays a solid foundation for the student, then plumbs the boundary between hardware and software as described and defined by architecture specifications, computer design principles, and best described in the author's words, "...where compilation (in software) ends and interpretation (in hardware) begins." The book discusses concepts of computer abstraction, technology, and performance issues. It initiates the process of "learning by evolution" of assembly language instructions and numbers, datapath and control concepts, pipelining and performance enhancement.
This book describes the design and implementation of the BSD operating system—previously known as the Berkeley version of UNIX. Today, BSD is found in nearly every variant of UNIX, and is widely used for Internet services and firewalls, timesharing, and multiprocessing systems. Readers involved in technical and sales support can learn the capabilities and limitations of the system; applications developers can learn effectively and efficiently how to interface to the system; systems programmers can learn how to maintain, tune, and extend the system. Written from the unique perspective of the system's architects, this book delivers the most comprehensive, up-to-date, and authoritative technical information on the internal structure of the latest BSD system.
As in the previous book on 4.3BSD (with Samuel Leffler), the authors first update the history and goals of the BSD system. Next they provide a coherent overview of its design and implementation. Then, while explaining key design decisions, they detail the concepts, data structures, and algorithms used in implementing the system's facilities. As an in-depth study of a contemporary, portable operating system, or as a practical reference, readers will appreciate the wealth of insight and guidance contained in this book.
Highlights of the book:
- Details major changes in process and memory management
- Describes the new extensible and stackable filesystem interface
- Includes an invaluable chapter on the new network filesystem
- Updates information on networking and interprocess communication
An authoratative guide to the 4.4 BSD internal structure (from the interface to kernels to the hardware), this book details concepts, algorithms, data structures, plus the major changes in process and memory management as well as the new extensible and stackable filesystem interface with in-depth information on the new network filesystem. This book is ideal for systems programmers, administrators, and application developers. Technical and sales support professionals will find vital information on the capabilities of 4.4BSD. Applications developers will pick up tips on interfacing with the system, while systems programmers can learn how to better maintain, tune, and extent the system.
Product Description Bestselling UNIX author W. Richard Stevens offers application developers and system programmers his professional, experience-based guidance on using the system call interface with C. In the first half of the book, Stevens describes more than 200 system calls and functions with a brief example program following each description. Having provided the basics, Stevens moves on to chapter-long examples. The book is applicable to all major UNIX releases, especially System V Release 4-including Solaris 2-and 4.4 BSD, including 386 BSD. From the Publisher A tutorial that you just shouldn't be without If you are an experienced C programmer with a working knowledge of UNIX, you cannot afford to be without this up-to-date tutorial on the system call interface and the most important functions found in the ANSI C library. Rich Stevens describes more than 200 system calls and functions; since he believes the best way to learn code is to read code, a brief example accompanies each description. Building upon information presented in the first 15 chapters, the author offers chapter-long examples teaching you how to create a database library, a PostScript printer driver, a modem dialer, and a program that runs other programs under a pseudo terminal. To make your analysis and understanding of this code even easier, and to allow you to modify it, all of the code in the book is available via UUNET. A 20-page appendix provides detailed function prototypes for all the UNIX, POSIX, and ANSI C functions that are described in the book, and lists the page on which each prototype function is described in detail. Additional tables throughout the text and a thorough index make Advanced Programming in the UNIX Environment an invaluable reference tool that all UNIX programmers - beginners to experts - will want on their bookshelves. Advanced Programming in the UNIX Environment is applicable to all major UNIX releases, especially System V Release 4 and the latest release of 4.3BSD, including 386BSD. These real-world implementations allow you to more clearly understand the status of the current and future standards, including IEEE POSIX and XPG3. This edition is now out of print.
