Feature Of Microprocessor 8086

  • Microprocessor 8086 is 16-bit processor i.e. ALU , Internal Register, instructions, word size and data bus.
  • 20-bit address bus so it can directly access 220 or 1048576 (1 MB) memory locations, but the 16-bit word is stored in 2 consecutive memory locations.
  • Microprocessor 8086 can generate 16-bit I/O address so it can access 216 or 64000 ports.
  • multiplexed address and data bus.
  • Microprocessor 8086 works on 5 MHz clock cycle.
  • Microprocessor 8086 able to perform bit, byte, word, block operations including DIV & MUL¬†.
  • operates in 2 modes : MAX. & MIN mode. Max. mode is used when in multiprocessor.
  • also supports multiprogramming¬†(time multiplexed fashion)
  • uses Queue to speed-up execution.
  • uses 14, 16-bit registers.
