Instruction Set - x86 (AMD, Intel)
https://datacadamia.com/computer/cpu/x86- 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).

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.See also x86 assembly

x86 is a family of complex instruction set computer (CISC) instruction set architectures initially developed by Intel based on the Intel 8086 microprocessor and its 8088 variant. The 8086 was introduced in 1978 as a fully 16-bit extension of Intel's 8-bit 8080 microprocessor, with memory segmentation as a solution for addressing more memory than can be covered by a plain 16-bit address. The t…

Bit manipulation instructions sets are extensions to the x86 instruction set architecture for microprocessors from Intel and AMD. The purpose of these instruction sets is to improve the speed of bit manipulation. All the instructions in these sets are non-SIMD and operate only on general-purpose registers. There are two sets published by Intel: BMI and BMI2; they were both …

Some R-Type instructions embed a small immediate value in the five low-order bits of OPX. Unused bits in OPX are always 0. R-type instructions include arithmetic and logical operations such as add and nor; comparison operations such as cmpeq and cmplt; the custom instruction; and other operations that need only register operands.

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
