 In April 1978, Intel introduced its first 16 bit
microprocessor. Production started in May, eventually,
the 8086 was officially released on June 8.
 The 8086 (also called iAPX 86 ) is a 16-
bit microprocessor chip designed by Intel.
It is a 16-bit up.
 8086 has a 20 bit address bus can access up to 220 memory
locations (1 MB).
 It can support up to 64K I/O ports.
 It provides 14, 16 -bit registers.
 Word size is 16 bits.
 It requires +5V power supply.
 A 40 pin dual in line package.
 Address ranges from 00000H to FFFFFH
 Memory is byte addressable - Every byte has
a separate address.
 8086 has two blocks BIU and EU.
• The BIU handles all transactions of data and addresses on
the buses for EU.
• The BIU performs all bus operations such as instruction
fetching, reading and writing operands for memory and
calculating the addresses of the memory operands.
• EU executes instructions from the instruction system byte
queue.
• BIU contains Instruction queue, Segment registers,
Instruction pointer, Address adder.
• EU contains Control circuitry, Instruction decoder, ALU,
Pointer
