Présentation de l'éditeur
This book is centered on Itanium architecture, the new 64-bit Explicitly Parallel Instruction Computing (EPIC) design by Hewlett-Packard and Intel in partnership. Itanium processors reflect a thoroughly new design. They support 64-bit open-source as well as proprietary operating systems and have been selected to replace existing RISC-based server and workstation lines by many of the industry's major system builders. The authors discuss the general principles of computer architecture with working examples. Also included are references, both print and electronic, to guide readers in finding related material. Along with the technical coverage are suggestions about the motivation and rationale for the Itanium architecture, as well as critique and demonstrate how to use its instruction set. Lastly, the book has sample Itanium programs that work with HP-UX assemblers, with GNU and Intel assemblers for Linux, and with the free Ski simulator from HP.
Quatrième de couverture
- Step-by-step guide to assembly language for the 64-bit Itanium processors, with extensive examples
- Details of Explicitly Parallel Instruction Computing (EPIC): Instruction set, addressing, register stack engine, predication, I/O, procedure calls, floating-point operations, and more
- Learn how to comprehend and optimize open source, Intel, and HP-UX compiler output
Itanium® Architecture for Programmers is a comprehensive introduction to the breakthrough capabilities of the new 64-bit Itanium architecture. Using standard command-line tools and extensive examples, the authors illuminate the Itanium design within the broader context of contemporary computer architecture via a step-by-step investigation of Itanium assembly language. Coverage includes:
- The potential of Explicitly Parallel Instruction Computing (EPIC)
- Itanium instruction formats and addressing modes
- Innovations such as the register stack engine (RSE) and extensive predication
- Procedure calls and procedure-calling mechanisms
- Floating-point operations
- I/O techniques, from simple debugging to the use of files
- Optimization of output from open source, Intel, and HP-UX compilers
An essential resource for both computing professionals and students of architecture or assembly language, Itanium Architecture for Programmers includes extensive printed and Web-based references, plus many numeric, essay, and programming exercises for each chapter.
