features or salient features of intel 80286 microprocess-or

1) The Intel 80286 is an advanced version of
      the 8086 microprocessor.
2) 80286 is designed for multiple and
     multitasking system .
3) It is high performance 16- bit        
     microprocessor , six times faster then
     the 8086 microprocessor.
4) It provides hardware and software logic
    to implement multitasking Os like
    windows .
5) It is upward compatible with 8086, 8088
    and 80186/80188 instruction set .
6) It provides an on : chip MMU. The MMU
   operates in two mode viz . Real mode and
   Protected mode .
7) It was used in IBM PC-AT .
8) It provides 24- bit address bus ; hence it
   can access 16 MB physical or
   semiconductor memory .
9) In protected mode, it can accept 1GB
   virtual memory .
10) The clock frequencies are 4MHz , 6MHz,
     8MHz , 10 MHz and 12.5 MHz .
11) It is housed in 68 pin leadless flat
      package .
12) It is 4 stage pipeline microprocessor .
13) It provides some additional dedicated
    interrupts .
14) The performance is 4 MIPS
    (Million Instructions per second ) .
15) The MMU also provides protection
     mechanism .
