what is a microprocessor? and what is it's work?

A microprocessor is a processing unite which process the data according to our work. it is fabricated on a small chip who’s size is decreasing day by day.

It is made of transistors through the size of transistor is decreasing that's why the size of microprocessors, microcontroller and, chips are also decreasing.

A microprocessor is a small processor. it processes the data which program is currently running in the system. a microprocessor consists of ALU(Arithmetic and Logical Unit), register sets(Array), and control unit.

IT takes the input  while processing it need some memory to fetch the related data and saves the output and gives us the output

processes the data in an instruction cycle.

there are three stapes in an instruction cycle.

1. Fetch

In this stape, the microprocessor fetches(reads) the codes wherever it is saved in the memory (probably copied to the main memory(RAM) before processing)

2. Decode

After fetching the data it decodes it. simply decoding is a process in which the computer let it know that what is going to be performed and what actions are to be taken by the system hardware.

3. Execute

decoding the data when the system knows that what to be done by the hardware of the system it simply execute those instructions.

Features of a Microprocessor

Here is a list of some of the most prominent features of any microprocessor −

Reliability

 − The failure rate of an IC in microprocessors is very low, hence it is reliable.

Power efficiency

 − Microprocessors are manufactured by using metal-oxide semiconductor technology, which has low power consumption.

Cost-effective

−The microprocessor chips are available at low prices and results in its low cost.

Size

− The microprocessor is of small size chip, hence is portable.

Usability

− The microprocessors are versatile as we can use the same chip in a number of applications by configuring the software program.
