Processors (CPU)

Processors (CPU)

Definition: A processor is the logic circuitry that responds to and processes the basic instructions that drive a computer. The four primary functions of a processor are fetch, decode, execute and write back. The arithmetic logic unit (ALU), which carries out arithmetic and logic operations on the operands in instructions.

Multi-Core Processor

The basic elements of a processor:
The floating point unit (FPU), also known as a math coprocessor or numeric coprocessor, a specialized coprocessor that manipulates numbers more quickly than the basic microprocessor circuitry can.
Registers, which hold instructions and other data. Registers supply operands to the ALU and store the results of operations.
L1 and L2 cache memory. Their inclusion in the CPU saves time compared to having to get data from random access memory (RAM).
Now-a-days Multicore processors are ruling the World.
