A processor is integrated circuitwhich has the logic circuit that responds to and processing the basicinstructions that drive a computer. That can be said as a performing actions asarithmetical, logical, input/output (I/O) and other basic instructions thatthey are passed from an operating system (OS).The four primary functions of aprocessor are fetch, decode, execute and write-back.The processors most of them oftoday’s world’s gadgets are multi-core which means that the integratedelectronic circuit contains two or more processors for enhanced performance,reduced power consumption and more efficient simultaneous processing ofmultiple tasks which is usually called parallel processing.
It can be illustrated with thefollowing example “Imagine a house is beingbuilt by a one person which can be said as single core “” The same house is beingbuilt by group of person which can be said as multi-core”Types of multi-core processors Dual Core ProcessorsDual-core Processor simply meansCentral Processing Units which has two complete execution cores per physicalprocessor. Dual core processors has two processors combined together and theircaches and cache controllers onto a single integrated circuit. Quad Core ProcessorsQuad-core processor is a chipwith four independent units called cores which read and execute tasks of centralprocessing unit (CPU) instructions such as add, move data, and branch.
Within the chip, each coreoperates in a conjunction with one other circuits such as cache, memorymanagement, and input/output (I/O) ports. The individual cores in a quad-coreprocessor will run multiple instructions at the same time, increasing overall speedfor programs compatible with parallel processing which can be double the speedof dual-core. Hexa Core ProcessorsHexa Core Processor is one of theother multi-core processor that is built with six cores. It can handle tasksfaster than the dual core and quad core processors which three times fasterthan dual core and 1.
5 times faster than quad-core. Octa Core ProcessorsThe octa core processors are madeup of eight independent cores to handle and perform task efficiently. Thisimplies that Octa-core processors can performs double faster than the quad coreprocessor.You might think that as a twosets of quad-core processors are present in a gadget, but it is still octa-core as you cannot call itdouble qual core processor.
The cores will split various tasks between themaccording to their types which performs smoothly and efficiently. Deca Core ProcessorsAs 2 cores are called adual-core, 4 cores are called a quad core,6 cores are called hexa-core and 8 cores are called octa-core. 10 cores are calledDeca-core which is made up of 10 complete independent units to handle andperform task very efficiently than other processors.
Having a deca coreprocessor along with an efficient processor type would really make gadgets to perform efficiently and superfaster than others.By this we can understand morecores means more processing speed This can be explained with smallexampleIf we have 1200 chocolates andeach chocolate for each person per day.2 persons complete it in 600days.4 persons complete it in 300days.6 persons complete it in 200days.
8 persons complete it in 150days.10 persons complete it in 100days. Here is number of persons performance is like performance of tasks by numberof cores.
