x86 instruction set Three main groups Data movement (from memory and between registers) Arithmetic operations (addition, subtraction, etc.) Control flow (jumps, function calls)

x86 is the name of an Instruction Set Architecture (ISA) that originated at Intel. The x86 Instruction Set Architecture (ISA) has evolved over time by: the addition of new Instruction (Machine Language) as well as the expansion to CPU - Word size (8, 16, 32 and 64-bit). The term x86 is derived from the fact that many of Intel's early processors ...

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.

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.

The geeksuite is intended for deeper research of x86 architectures' instruction set. This includes geek32, geek64, and geekeditions (by opcode) and geek32-abc, geek64-abc, and geek-abceditions (by mnemonic). More on the purpose and use of this suite see close below.
