Mar 1, 2020 · Raffzahn ’s answer lists the early manuals in the history of x86 documentation. To answer more specifically concerning version 71 of the Intel ® 64 and IA-32 Architectures Software Developer’s Manual, see order number 252046, Documentation Changes: version 1 of the manual was released in 2002, to document the first 64-bit x86 Intel CPUs.

microprocessor based on its “x86-64” instruction set. As the name implies, x86-64 is an evolution of the Intel instruction set to 64 bits. It maintains full backward compatibility with IA32, but it adds new data formats, as well as other features that enable higher capacity and higher performance. With x86-64, AMD

x86 integer instructions [ edit] Below is the full 8086/8088 instruction set of Intel (81 instructions total). Most if not all of these instructions are available in 32-bit mode; they just operate on 32-bit registers ( eax, ebx, etc.) and values instead of their 16-bit ( ax, bx, etc.) counterparts.

Jan 10, 2019 · Assembly language is also specific to the architecture (Here, we discuss Intel x86 and x64), whereas a language like C is portable. Assembly has a small (comparatively) set of commands: Commands that move data between various places Commands that execute mathematic algorithms (simple to complex) Commands that check conditions (like if)

Aug 6, 2021 · The Intel 64 and IA-32 Architectures Software Developer’s Manual volume 2 states "The single-byte-opcode forms of the INC/DEC instructions are not available in 64-bit mode. INC/DEC functionality is still available using ModR/M forms of the same instructions (opcodes FF/0 and FF/1)." Opcode . The opcode can be 1, 2 or 3 bytes in length.

Intel Manuals. The Intel Corporation provides many useful documents on the Pentium 4 Processor Technical Documentation ... (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 ...

Dec 14, 2021 · The x64 provides new variants of the MOV instruction that can handle 64-bit immediate constants or memory addresses. The x64 also provides a new instruction to sign-extend 32-bit operands to 64 bits. Ordinary MOV operations into 32-bit subregisters automatically zero extend to 64 bits, so there is no MOVZXD instruction.
