A processor is integrated circuit
which has the logic circuit that responds to and processing the basic
instructions that drive a computer. That can be said as a performing actions as
arithmetical, logical, input/output (I/O) and other basic instructions that
they are passed from an operating system (OS).The four primary functions of a
processor are fetch, decode, execute and write-back.
The processors most of them of today’s
world’s gadgets are multi-core which means that the integrated electronic
circuit contains two or more processors for enhanced performance, reduced power
consumption and more efficient simultaneous processing of multiple tasks which
is usually called parallel processing.
It can be illustrated with the
“Imagine a house is being
built by a one person which can be said as single core ”
” The same house is being
built by group of person which can be said as multi-core”
Types of multi-core processors
Dual Core Processors
Dual-core Processor simply means
Central Processing Units which has two complete execution cores per physical
processor. Dual core processors has two processors combined together and their
caches and cache controllers onto a single integrated circuit.
Quad Core Processors
Quad-core processor is a chip
with four independent units called cores which read and execute tasks of central
processing unit (CPU) instructions such as add, move data, and branch.
Within the chip, each core
operates in a conjunction with other circuits such as cache, memory management,
and input/output (I/O) ports. The individual cores in a quad-core processor will
run multiple instructions at the same time, increasing overall speed for programs
compatible with parallel processing which can be double the speed of dual-core.
Hexa Core Processors
Hexa Core Processor is one of the
other multi-core processor that is built with six cores. It can handle tasks
faster than the dual core and quad core processors which three times faster
than dual core and 1.5 times faster than quad-core.
Octa Core Processors
The octa core processors are made
up of eight independent cores to handle and perform task efficiently. This
implies that Octa-core processors can performs double faster than the quad core
You might think that as a two
sets of quad-core processors are present in a gadget, but it is still octa-core as you cannot call it
double qual core processor. The cores will split various tasks between them
according to their types which performs smoothly and efficiently.
Deca Core Processors
As 2 cores are called a
dual-core, 4 cores are called a quad core,
6 cores are called hexa-core and 8 cores are called octa-core. 10 cores are
called Deca-core which is made up of 10 complete independent units to handle
and perform task very efficiently than other processors. Having a deca core
processor along with an efficient processor
type would really make gadgets to perform efficiently and super faster than
By this we can understand more
cores means more processing speed
This can be explained with small
If we have 1200 chocolates and
each chocolate for each person per day.
2 persons complete it in 600
4 persons complete it in 300
6 persons complete it in 200
8 persons complete it in 150
10 persons complete it in 100 days.
Here is number of persons performance is like performance of tasks by number
