INTRODUCTION TO MICROPROCESSOR

 MICROPROCESSOR

                                        The microprocessor is a clock driven ,programmable,register based device.                                         

       the microprocessor reads the data i.e.binary instruction from the memory .it accepts this binary data as input and process the data according to the instructions and computes the result as output.

       Any such machine that does some process (implementation, process) is called processor.
The CPU is a very complex (complex) set of Electronic Circuit that executes the program Instruction collected.
Microprocessor is an important part of PC (Personal Computer) that processes data. CPU stands for Central Processing Unit. The microprocessor is called the CPU that fits on top of a microchip and is made of microchip silicon which is equipped with millions of transistors and other components very well. There is a very complected switching circuit inside it, which executes the instructions very fast, it is the brain of the computer, its Called "Brain" Of Computer. It takes input from the user, processes it and gives appropriate output.
Or you say it like this,
The CPU collects the Raw Data as an Input through the Input Device, then converts that Raw Data into Use Full Information as a Process through the Processor, and finally gets the final result through the Output Device. .


We hope you have understood this well, let us understand it through Real Life Example and in a good way.
For example: -

You took an orange, put it in the juice mixer grinder, then you turned on the grinder, you will get it by grinding the orange in the grinder, you put it in the grinder, Orange like Raw Data put it in the grinder like Input, then the Grinder machine will grind it like Process Finally You will get the result in the juice form like Output.

It is very important to understand how CPU works and is done inside it. So let's try to understand it.


There are two Buses inside the CPU, the first bus is called Data Bus and the second bus is called Address Bus. It connects both buses with I / O (Input Output) Bus, and Memory and Peripherals Connect through I / O Bus. Memory, where there is a Program Store called RAM, and Peripherals like Keyboard, Mouse etc.

Components Of CPU: -

The CPU is made up of a number of Chips that work with each other. The CPU has two typical components, the first ALU (Arithmetic and Logic Unit) and the second CU (Control Unit).

    The ALU Arithmetic Logic Unit performs basic Arithmetic and Logic Operation, Arithmetic Operation such as Addition, Subtraction, Multiplication and Division, and Logic Operation such as NOT, AND, and OR.
    This part of the CU Control Unit CPU controls Input and Output Devices.
The Control Unit is connected to a Clock (a piece of Crystal which is very fast), it issues an Instruction on each 'Tick' of the Clock, if you have a very Fast Clock in your computer, this means that Control The unit can release more instructions in a short time, that is why the computer works more in less time, it is really very fast, if a computer's clock speed is 3 GHz, it means that the control unit is 3 in a second Billion Instructions can issue, Every Second ....
