- Processor is the electronic circuit.
- Processor is the heart of the Computer.
- Processor carries instructions of a computer.
- Processor performs the following :
- Fetch : Retrieves the instruction.
- Decode : Converts the information.
- Execute : Delivers the result.
- CPU is looks as below.
- Below is the block diagram of CPU.
Terms used Most:
ALU:
Performs Integrated Arithmetic and Bit wise logic Operations.
Clock Speed/ Clock Rate:
Used for determining the speed of the processor for executing single instruction(i.e.,Cycle).
Clock Speed is Measured in MHz or GHz.
1 MHz - 1 Million Cycles Per Second
1 GHz - 1 Thousand Million Cycles Per Second.
Registers:
A register may hold the details of the preforming instruction.
It stores in the form of Address and Format.
Cache Memory:
Used to store the frequently called memory from the ROM in CPU.
Core:
One Single CPU with multiple Processors.
A single work is split into the many parts.
Basic Block diagram of Cores
Inside the CPU with 4 Cores(I7 Processor)
Unlocked Processors :
Processor clock speed can be adjusted for some extent.
Multi Processors:
A Mother Board With More than one processor is called the multi processor.
