• x86 - Wikipedia

    en.wikipedia.org/wiki/X86 x86 is a family of 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 term "x86" came into being because the ...

  • x86 - Simple English Wikipedia, the free encyclopedia

    simple.wikipedia.org/wiki/X86 x86 is a term used to describe a CPU instruction set compatible with the Intel 8086 and its successors, including the Pentium and others made by Intel and other companies. This is the CPU architecture used in most desktop and laptop computers. Many 21st century workstations and servers also use x86 processors. In 1985, the original 16 bit x86 architecture was extended to 32 bits with the ...
  • What is X86? - Computer Hope

    www.computerhope.com/jargon/x/x86.htm x86 is an Intel CPU architecture that originated with the 16-bit 8086 processor in 1978. Today, the term "x86" is used generally to refer to any 32-bit processor compatible with the x86 instruction set.. In its 40 years of existence, the x86 architecture has added many new features while remaining almost entirely backward-compatible, which is a remarkable achievement.
  • x86-64 - Wikipedia

    en.wikipedia.org/wiki/X86-64 x86-64 (also known as x64, x86_64, AMD64 and Intel 64) is the 64-bit version of the x86 instruction set.It introduces two new modes of operation, 64-bit mode and compatibility mode, along with a new 4-level paging mode. With 64-bit mode and the new paging mode, it supports vastly larger amounts of virtual memory and physical memory than is possible on its 32-bit predecessors, allowing programs ...
  • What is x86 Architecture? - Definition from Techopedia

    www.techopedia.com/definition/5334/x86-architecture x86 Architecture: The x86 architecture is an instruction set architecture (ISA) series for computer processors. Developed by Intel Corporation, x86 architecture defines how a processor handles and executes different instructions passed from the operating system (OS) and software programs. The “x” in x86 denotes ISA version.

  • Why does x86 mean 32-bit? | Yahoo Answers

    answers.yahoo.com/question/index x86 started out as a 16-bit instruction set for 16-bit processors (the 8086 and 8088 processors), then was extended to a 32-bit instruction set for 32-bit processors (80386 and 80486), and now has been extended to a 64-bit instruction set for 64-bit processors. It used to be written as 80x86 to reflect the changing value in the middle of the ...
  • What Does x64 and x86 Mean? - Digital Point

    forums.digitalpoint.com/threads/what-does-x64-and-x86-mean.674631 x86 = 32bit x64 = 64bit As the x86 term became common after the introduction of the 80386, it usually implies a binary compatibility with the 32-bit instruction set of the 80386. This may sometimes be emphasized as x86-32 to distinguish it either from the original 16-bit x86-16 or from the newer 64-bit x86-64 (also called x64).
  • Guide to x86 Assembly - Yale University

    www.cs.yale.edu/flint/cs421/papers/x86-asm/asm.html The x86 processor maintains an instruction pointer (EIP) register that is a 32-bit value indicating the location in memory where the current instruction starts. Normally, it increments to point to the next instruction in memory begins after execution an instruction. The EIP register cannot be manipulated directly, but is updated implicitly by ...
