A microprocessor incorporates the functions of a computer's central processing unit (CPU) on a single integrated circuit (IC, or microchip). It is a multipurpose, programmable, clock-driven, register based electronic device that accepts binary data as input, processes it according to instructions stored in its memory, and provides results as output.
To understand how a microprocessor works, it is helpful to look inside and learn about the logic used to create one. You can also learn about assembly language - the native language of a microprocessor - and many of the things that engineers can do to boost the speed of a processor.
A microprocessor executes a collection of machine instructions that tell the processor what to do. Based on the instructions, a microprocessor does three basic things:
There may be very sophisticated things that a microprocessor does, but those are its three basic activities.
This is about as simple as a microprocessor gets. This microprocessor has:
Let's assume that both the address and data buses are 8 bits wide in this example.
Here are the components of this simple microprocessor:
There would also be control lines from the instruction decoder that would:
Coming into the instruction decoder are the bits from the test register and the clock line, as well as the bits from the instruction register.
Works as arithmatic and logical unit
Give signal for time selection and control
Execute the program which store in the computer memory
Make co ordination with input and output device
Microprocessor is nothing but CPU built on a single IC.thus as we know that CPU is the brain of the computer thus its all the microprocessor which performs any kind of opertion in the computer be it any arithmetic operation fro instance.

Microprocessors handle just about everything in computers. I'll break this down just a bit for you. For example:
CPU: Central Processing Unit- This is the biggest "beef" of your computer, and performs almost all of the calculations, instructions, and addressing necessary in order for a computer to actually "compute" or function. This dictates what data does, where it goes, and how it is handled.
Northbridge- The NB is built into the CPU on newer processors, but it traditionally was set on the motherboard. This is a microprocessor that handles memory addressing, and acts as a liaison between expansion slots and the CPU, particularly when it comes to your RAM. This piece of hardware is also vital to a computer, and computers do not function without some form of a NB.
Microprocessor Controllers- Built into basically everything, these minor processors control the function of smaller computer parts. Individual RAM modules have a controller on them, which tells the part itself how to interpret data that comes to it. The same applies to Network Interface Cards, Hard Drives, Graphics Cards, USB Hubs, and essentially anything else that can be connected to a computer.
Guess you could say microprocessors are what make computers computers!

The clock signal in a microprocessor allows synchronization of several components of the microprocessor. The correctness of the computation of the microprocessor depends upon efficient and balanced distribution of the clock signal. The clock generator generates the clock signal.

The role of a microprocessor in a photocopier controls the display on the front of the machine. Also the microprocessor sends signal to the motor to move parts of the photocopier, so that the paper can come out.

How does a microprocessor decode?
The plural of microprocessor is microprocessors.
Microprocessor is a single chip processor.
The microprocessor is a piece of hardware, not software. Windows 7 doesn't supply a microprocessor.
