MASM uses the standard Intel syntax for writing x86 assembly code. The full x86 instruction set is large and complex (Intel's x86 instruction set manuals comprise over 2900 pages), and we do not cover it all in this guide. For example, there is a 16-bit subset of the x86 instruction set. Using the 16-bit programming model can be quite complex.

x86 instruction set The full x86 instruction set is large and complex But don’t worry, the core part is simple The rest are various extensions (often you can guess what they do, or …

The reference is primarily based on Intel manuals as Intel is the originator of x86 architecture. Additionally, it describes undocumented instructions as well. On appropriate places, it gives a notice if an opcode act differently on AMD architecture. Support for Cyrix, NexGen etc. specific instructions is not scheduled at all. HTML Editions

We will uses the standard AT&T syntax for writing x86 assembly code. The full x86 instruction set is large and complex (Intel's x86 instruction set manuals comprise over 2900 pages), and we do not cover it all in this guide. For example, there is a 16-bit subset of the x86 instruction set. Using the 16-bit programming model can be quite complex.

Sep 09, 2017 · The x86-64 instructions are encoded one by one as a variable number of bytes for each. Each instruction’s encoding consists of: an opcode a register and/or address mode specifier consisting of the ModR/M byte and sometimes the scale-index-base (SIB) byte (if required) a displacement and an immediate data field (if required)

Mar 01, 2022 · These manuals describe the architecture and programming environment of the Intel® 64 and IA-32 architectures. Electronic versions of these documents allow you to quickly get to the information you need and print only the pages you want. The Intel® 64 and IA-32 architectures software developer's manuals are now available for download via one ...

x86-64 Instructions Set CPU instructions The general-purpose instructions perform basic data movement, arithmetic, logic, program flow, and string operations which programmers commonly use to write application and system software to run on Intel 64 and IA-32 processors.
