Microprocessor is the heart, the soul as wellas the brain of computer. In fact it is itself acomputer.

Microprocessor is the single chip integratingall the function of CPU


3/19

Central processing unit which co-ordinate allthe function of computer.

Generates timing signal, sends and receives

data to and from every peripheral used inside

or outside the computer. The command required to do this are fed into

the device in the form of current variation

which are converted into meaningfulinstruction by the use of boolean logic

system.

It divides the function into two categories,

logical function and processing function.


4/19

The ALU and Control unit perform these

function respectively.

The information is communicated through

bunch of wires called BUSES.


5/19

SHOCKELY BRATTAIN and BARDEEN

are the man behind the invention of

microprocessor in 1947.

Function of this large component can be

performed easily by arranging group of

transistor on a single chip.

This is called INTEGRATED CHIP(IC).And the man behind this was JACK KILBY.

INTEL 4004 Introduced in 1971.

It was the first microprocessor by Intel.

It was a 4-bit p. It had 2,300 transistors.

It could execute around 60,000 instructions

per second.

Video game

Small microprocessor based system.


8/19

8-BIT MICROPROCESSOR

In late 1971 microprocessor enter into thecommercial field.

Intel launch 8008 microprocessor in late 1971and in 1973 launches upgraded model of itnamed as 8080.

8008 8080

I. It has processing

speed of20s/instruction.

II. It is capable to

address 16 k ofmemory.

I. It has processing

speed of2s/instruction.

II. It is capable to

address 64 k ofmemory.


10/19

Introduced in 1976.

Its data bus is 8-bit and address is 16 bit.

It could access 64k memory.

It could execute 7,69,230 instructions /sec.

It has 6500 transistors.


11/19

To work with larger application , evolution of

16 bit p took place.


12/19

16 BIT p

Introduced in 1978.

Its data bus is 16 bit and address bus is 20 bit.

It has 29,000 transistor and can access 2.5million instruction/sec

It could access 1MB of memory

Example:- 8086 , 8088 , 80186 , 80286 p.


13/19

Introduced in 1986.

Its data bus and address bus are of 32

bit. It has 2,75,000 transistors.

It could access 4 GB of memory.
