The 8086 [3] (also called iAPX 86) [4] is a 16-bit microprocessor chip designed by Intel between early 1976 [citation needed] and June 8, 1978, when it was released. [5] The Intel 8088, released July 1, 1979, [6] is a slightly modified chip with an external 8-bit data bus (allowing the use of cheaper and fewer supporting ICs), [note 1] and is notable as the processor used in the original IBM ...
Intel's second generation of 32-bit x86 processors, introduced built-in floating point unit (FPU), 8 KB on-chip L1 cache, and pipelining. Faster per MHz than the 386. Small number of new instructions. P5 original Pentium microprocessors, first x86 processor with super-scalar architecture and branch prediction. P6
In marketing, iAPX (Intel Advanced Performance Architecture [1]) was a short lived designation used for several Intel microprocessors, including some 8086 family processors. [2] Not being a simple initialism seems to have confused even Intel's technical writers as can be seen in their iAPX-88 Book where the asterisked expansion shows iAPX to ...
Below is the full 8086/8088 instruction set of Intel (81 instructions total). [2] These instructions are also available in 32-bit mode, in which they operate on 32-bit registers (eax, ebx, etc.) and values instead of their 16-bit (ax, bx, etc.) counterparts.

During the mid-1980s NEC and Intel had a long-running US federal court case about microcode copyright. [26] NEC had been acting as a second source for Intel 8086 CPUs with its NEC μPD8086, and held long-term patent and copyright cross-licensing agreements with Intel. In August 1982 Intel sued NEC for copyright infringement over the microcode ...
The Intel x86 computer instruction set architecture has supported memory segmentation since the original Intel 8086 in 1978. It allows programs to address more than 64 KB (65,536 bytes) of memory, the limit in earlier 80xx processors.
The great leap toward 64-bit computing and the maintenance of backward compatibility with 32-bit and 16-bit software enabled the x86 architecture to become an extremely flexible platform today, with x86 chips being utilized from small low-power systems (for example, Intel Quark and Intel Atom) to fast gaming desktop computers (for example ...
