Internally, the Athlon is a fully seventh generation x86 processor, the first of its kind.

However, MUL and DIV are special cases, other arithmetic-logical instructions ( ADD, SUB, CMP, AND, OR, XOR, TEST ) may specify any of the eight registers EAX, ECX, EDX, EBX, ESP, EBP, ESI, EDI as the accumulator ( i. e. left operand and destination ); x86 is thus a fairly general register architecture, despite being based on an accumulator model.

It is available on Linux and BSD for Intel x86 ; Linux for Alpha ; Mac OS X for Intel x86 and PowerPC ; and Solaris, IRIX, and HP-UX on their native platforms.

Winelib, a part of the Wine project, is the inverse of Cygwin-it is a free and open source compatibility layer for Unix-like operating systems on the x86 or x86-64 architecture that can allow programs written for Microsoft Windows to run on Unix-like operating systems.

: The best known family of operating systems named " DOS " is that running on IBM PCs type hardware using Intel x86 CPUs or their compatible cousins from other makers.

IA-32 ( Intel Architecture, 32-bit ), also known as x86-32, i386 or x86, is the CISC instruction-set architecture of Intel's most commercially successful microprocessors, and was first implemented in the Intel 80386 as a 32-bit extension of x86 architecture.

An interesting feature of this processor is that it was the first x86 processor with protected mode.

The legacy of the 8086 is enduring in the basic instruction set of today's personal computers and servers ; the 8086 also lent its last two digits to later extended versions of the design, such as the Intel 286 and the Intel 386, all of which eventually became known as the x86 family.

As the original implementation of the 32-bit extension of the 8086 architecture, the 80386 instruction set, programming model, and binary encodings are still the common denominator for all 32-bit x86 processors, this is termed x86, IA-32, or i386-architecture, depending on context.

The modern-day ubiquitous x86 architecture belongs to this category as well, but octal is rarely used on this platform, although certain properties of the binary encoding of opcodes become more readily apparent when displayed in octal, e. g. the ModRM byte, which is divided into fields of 2, 3, and 3 bits, so octal can be useful in describing these encodings.

As this is written, both single and dual x86 CPUs and the StrongARM family are supported.

A simple example ( in the x86 architecture ) is

This flaw in the Pentium FPU was quickly verified by other people around the Internet, and became known as the Pentium FDIV bug ( FDIV is the x86 assembly language mnemonic for floating-point division ).

( A similar scheme is employed to run 68K software on modern x86 Alpha Microsystems machines.

" Rosetta " is the name of a " lightweight dynamic translator " that enables applications compiled for PowerPC processor to run on Apple systems using an x86 processor.

Stanford University's Folding @ home project is a distributed computing research effort which uses its approximately 5 petaFLOPS (~ 10 x86 petaFLOPS ) of computing power to attempt to model the tertiary ( and quaternary ) structures of proteins, as well as other aspects of how and why proteins fold into the inordinately complex and varied shapes they take.

x86 is a series of computer microprocessor instruction set architectures based on the Intel 8086 CPU.

The term is not synonymous with IBM PC compatibility as this implies a multitude of other computer hardware ; embedded systems as well as general-purpose computers used x86 chips before the PC-compatible market started, some of them before the IBM PC itself.

Although most x86 processors used in new personal computers and servers have 64-bit capabilities, to avoid compatibility problems with older computers or systems, the term x86-64 ( or x64 ) is often used to denote 64-bit software, with the term x86 implying only 32-bit.

The AGP slot first appeared on x86 compatible system boards based on Socket 7 Intel P5 Pentium and Slot 1 P6 Pentium II processors.

Similar I / O-port schemes were used in the backward compatible Zilog Z80 and Intel 8085 as well as the closely related x86 families of microprocessors.

Itanium failed to make significant inroads against IA-32 or RISC, and then suffered from the successful introduction of x86-64 based systems into the high-end server market, systems which were more compatible with the older x86 applications.

* < tt > std </ tt >, the set direction flag instruction on x86 compatible CPUs, opposite of < tt > cld </ tt >

AMD Athlon ( early version )-another technically different, but fully compatible, x86 implementation.

In certain applications, where small size or power efficiency are not primary concerns, the components used may be compatible with those used in general purpose x86 personal computers.

Developers began to target the P5 Pentium processor family almost exclusively with x86 assembly language optimizations which led to the usage of terms such as Pentium compatible processor for software requirements.

Since a primary design specification of x86 microprocessors is that they are fully backwards compatible with software written for all x86 chips before them, the 286 chip was made to start in ' real mode ' – that is, in a mode which turned off the new memory protection features, so that it could run operating systems written for the 8086 and the 80186.

Before the 386 the only way to switch from protected mode back to real mode was to reset the processor ; after a reset it always starts up in real mode to be compatible with earlier x86 CPUs back to the 8086.

** Wintel, that is, Intel x86 or compatible personal computer hardware with Windows operating system

Geode ( processor ) | The AMD Geode is an x86 compatible system on a chip

Wintel is a portmanteau of Windows and Intel, referring to personal computers using Intel x86 compatible processors running Microsoft Windows.

However, Wintel is now commonly used to refer to a system running a modern Microsoft operating system on any modern x86 compatible CPU, manufactured by either Intel or AMD.

It is fully backwards compatible with 16-bit and 32-bit x86 code.

The x86-64 specification is distinct from the Intel Itanium ( formerly IA-64 ) architecture, which is not compatible on the native instruction set level with the x86 architecture.

This tool is a Syslinux com32 module that displays low-level information for any x86 compatible system.

* Direction flag, a flag stored in the FLAGS register on all x86 compatible CPUs

This memory model has remained ever since in the x86 machines, which now provide multi-mode operation and rarely operate in the compatible segmented mode anyway.

Within the x86 architectures, when operating in the real ( compatible ) mode, physical address is computed as:

* Zet: an x86 compatible core

Although the file format is the same in MS-DOS and CP / M,. COM files for the two operating systems are not compatible ; MS-DOS COM files contain x86 instructions and possibly MS-DOS system calls, while CP / M COM files contain 8080 instructions ( programs restricted to certain machines could also contain additional instructions for 8085 or Z80 ) and CP / M system calls.
