The 8086 is a 16-bit microprocessor chip designed by Intel in 1978 - the introduction to the x86 architecture. Shortly later the 8088 was introduced with an external 8-bit bus, allowing the use of cheap chipsets. It was based on the design of the 8080 with a similar register set, but was expanded to 16 bits.
It featured four 16-bit general registers, which could also be accessed as eight 8-bit registers, and four 16-bit index registers (including the stack pointer).
The processor runs at clock speeds between 4.77 (in the original IBM PC) and 10 MHz.
The 8086 was cloned by the NEC V20, NEC V30 and NEC V50. There are mathematical coprocessors for the 8086, the 8087.
For more Information on x86 processors please refer to the x86 processor FAQ or CPU+Mainboard FAQ (german).
