 Wikinfo | X86
x86 or Intel 80x86 is the generic name of an architecture of microprocessors first developed and manufactured by Intel, also manufactured at various stages by AMD, Cyrix, NEC, IDT, Transmeta (that uses it in PDAs too, see Crusoe) (arguably) and sundry other makers at various stages in its nearly 25-year history.
The architecture of Intel's 32-bit x86 processors is sometimes known as IA-32.
Intel's IA-64 architecture used in its Itanium processors is related to x86, but incompatible with its instruction set.

 Art of Assembly: Chapter Fourteen-3
Shortly after the release of the 80486, Intel introduced the 80486sx CPU that was an 80486 without the built-in FPU.
Intel wanted to designed an FPU that could work with the majority of the software out there (keep in mind, the IBM PC was three to four years away when Intel began designing the 8087, they couldn't rely on that "mountain" of software available for the PC to make their chip popular).
Intel wanted as many applications as possible to work with as few changes as possible on their 80x87 FPUs, so they added a special register, the FPU control register, that lets the user choose one of several possible operating modes for the 80x87.

 Chapter Eleven Real Arithmetic
When the 8086 CPU first appeared in the late 1970's, semiconductor technology was not to the point where Intel could put floating point instructions directly on the 8086 CPU.
When Intel designed the 80x87 (and, essentially, the IEEE floating point standard), there were no standards in floating point hardware.
Intel wanted as many applications as possible to work with as few changes as possible on their 80x87 FPUs, so they added a special register, the FPU control register, that lets the user choose one of several possible operating modes for their FPU.
