No prior knowledge of x86 code is needed, although it makes the transition easier. x64 is a generic name for the bit extensions to Intel‟s and AMD‟s bit x86 instruction set architecture (ISA). AMD introduced the first version of x64, initially called x and later renamed AMD Intel named their implementation IAe and then EMT L x Assembly CSE, Winter Intel/AMD x86 Evolution: Milestones Name Date Transistors MHz 29K First bit Intel processor. Basis for IBM PC DOS 1 MB address space K First bit Intel processor, referred to as IA32 Added “flat addressing,” capable of running Unix Pentium (P5) M 60Missing: manual. Intel 64 Architecture. A recapitulation of the architecture's features can be found in chapter Intel® 64 Architecture in manual Basic Architecture: Intel 64 architecture increases the linear address space for software to 64 bits and supports physical address space up to 40 bits.
the Intel 64 and IA Architectures Software Developer’s Manuals‘ “APPENDIX B INSTRUCTION FORMATS AND ENCODINGS” is a good reference. x Instruction Encoding is another very good page from OSDev as a quick reference. x86 and amd64 instruction reference. Derived from the May version of the Intel® 64 and IA Architectures Software Developer’s Manual. Last updated THIS REFERENCE IS NOT PERFECT. It's been mechanically separated into distinct files by a dumb script. The Intel® 64 and IA architectures software developer's manuals are now available for download via one combined volume, a four volume set or a ten volume set. All content is identical in each set; see details below.
In this way the author of the code which will be hidden can select operations based on the number of opcode bytes. Although the intel/AMD bit instruction set. NOTE: The Intel 64 and IA Architectures Software Developer's Manual consists of five volumes: Basic Architecture, Order Number ; Instruction Set.
