Central Processing Unit (CPU)
Central Processing Unit (CPU) (Short: Central processor)
The central processing unit carries out the instructions of a computer program by performing the basic arithmetic, logic, controlling, and input/output (I/O) operations specified by the instructions.
To function properly, the central processor relies on: Memory, secondary storage, data and address buses
and the systems clock.
The central processing unit has 2 components:
-The control Unit: extracts instructions from memory and decodes and executes them.
-The arithmetic Logic Unit (ALU): handles arithmetic and logical operations.
The central processor contains internal memory units, which are called registers. And these registers contain data, instructions, counters and addresses used in the arithmetic Logic Unit informations processing.
Some computers utilize two or more processors.
These consist of separate physical central processing units, located side by side on the same board or on separate boards.
Each central processing unit has an independent interface, separate cache, and individual paths to the system front-side bus. And multiple processors are ideal for intensive multithreading or other parallel computing techniques.
Extra:
A multi-core processor is a computer processor integrated circuit with two or more separate processing units, called cores.
And with a chip multiprocessor the cores are integrated onto a single integrated circuit.
