CPU Manuals

The Intel Corporation provides many useful documents on the

Pentium 4 Processor Technical Documentation page.

Especially useful for helping you to understand the machine dependent code of MINIX 3 on an IBM-PC compatible machine will be the Manuals section. As of October 2004 the following manuals are available as PDF files (read with Adobe Acrobat or Ghostview):

• IA-32 Intel Architecture Optimization Reference Manual
• IA-32 Intel Architecture and Intel. Extended Memory 64 Software Developer's Manual Documentation Changes
• IA-32 Intel Architecture Software Developer's Manual Volume 1: Basic Architecture
• IA-32 Intel Architecture Software Developer's Manual Volume 2A: Instruction Set Reference, A-M
• IA-32 Intel Architecture Software Developer's Manual Volume 2B: Instruction Set Reference, N-Z
• IA-32 Intel Architecture Software Developer's Manual Volume 3: System Programming Guide
• The Software Optimization Cookbook

These are all downloadable as PDF files (read with Adobe Acrobat or Ghostview). A CD-ROM containing the complete set of manuals can also be ordered from Intel.

All AMD processors for IBM-PC have the same IA-32 architecture as Intel processors. The differences are in multimedia technology, where AMD processors have 3DNOW! and other things… And the next AMD processor (x86-64) will be different, but still compatible with IA-32. So, the Intel docs will also help you understand and program for AMD processors. But, AMD provides manuals too – they are available at the

AMD64 Architecture Tech Docs

page. These AMD manuals were available as of October 2004:

• AMD64 Architecture Programmer's Manual Volume 1: Application Programming
• AMD64 Architecture Programmer's Manual Volume 2: System Programming
• AMD64 Architecture Programmer's Manual Volume 3: General-Purpose and System Instructions
• AMD64 Architecture Programmer's Manual Volume 4: 128-Bit Media Instructions
• AMD64 Architecture Programmer's Manual Volume 5: 64-Bit Media and x87 Floating-Point Instructions

Note that the syntax of the assembly language used in MINIX 3 is different from Intel's. The MINIX 3 syntax is consistent with assembly languages used by other UNIX-derived systems. Other links on the page point to articles describing assembly language syntax.
