A processor is an integrated electronic circuit that performs the calculations that run a computer. A processor performs arithmetical, logical, input/output (I/O) and other basic instructions that are passed from an operating system (OS). Most other processes are dependent on the operations of a processor.
The central processor of a computer is also known as the CPU, or "central processing unit." This processor handles all the basic system instructions, such as processing mouse and keyboard input and running applications. Most desktop computers contain a CPU developed by either Intel or AMD, both of which use the x86 processor architecture. Mobile devices, such as laptops and tablets may use Intel and AMD CPUs, but can also use specific mobile processors developed by companies like ARM or Apple.
Modern CPUs often include multiple processing cores, which work together to process instructions. While these "cores" are contained in one physical unit, they are actually individual processors. In fact, if you view your computer's performance with a system monitoring utility like Windows Task Manager or Activity Monitor you will see separate graphs for each processor. Processors that include two cores are called dual-core processors, while those with four cores are called quad-core processors. Some high-end workstations contain multiple CPUs with multiple cores, allowing a single machine to have eight, twelve, or even more processing cores.
Different types of the processsor are:
1. Central processing unit (CPU) - the hardware within a computer that executes a program.
2. Microprocessor - central processing unit contained on a single integrated circuit
3. Application-specific instruction set processor (ASIP) - component used in system-on-a-chip design
4. Graphics processing unit (GPU) - processor designed for doing dedicated graphics-rendering computations
5. Physics processing unit (PPU) - dedicated microprocessor designed to handle the calculations of physics
6. Digital signal processor (DSP) - microprocessor designed specifically for digital signal processing
7. Image processor - special DSP used for image processing in digital cameras, mobile phones or other devices
8. Network processor - microprocessor specifically targeted at the networking application domain
9. Multi-core processors - ingle component with two or more independent CPUs (called "cores") on the same chip carrier
10. Front-end processor - helper processor for communication between a host computer and other devices
11. Coprocessor
Accordance with the number of core:
1.single core processor:-A single-core processor is a microprocessor with a single core on a chip, running a single thread at any one time. For example, Intel released a Core 2 Solo and Core 2 Duo, and one would refer to the former as the 'single-core' variantProcessors remained single-core until it was impossible to achieve performance gains from the increased clock speed and transistor count allowed by Moore's law (there were diminishing returns to increasing the depth of a pipeline, increasing CPU cache sizes, or adding execution units).
2.Multi-core processor:-
A multi-core processor is a single computing component with two or more independent processing units called cores, which read and execute program instructions.A multi-core processor implements multiprocessing in a single physical package.Multi-core chips also allow higher performance at lower energy. This can be a big factor in mobile devices that operate on batteries. Since each core in a multi-core CPU is generally more energy-efficient, the chip becomes more efficient than having a single large monolithic core. This allows higher performance with less energy. The Intel Core 2 Duo E6750 dual-core processor is an example of a symmetric multi-core processor.
3. Many-core processor:-
These are specialist multi-core processors designed for a high degree of parallel processing, containing a large number of simpler, independent processor cores Manycore processors are used extensively in embedded computers and high-performance computing. They are optimised from the outset for a higher degree of explicit parallelism, and for higher throughput (or lower power consumption) at the expense of latency and lower single thread performance. Manycore processors are specialist multi-core processors designed for a high degree of parallel processing, containing a large number of simpler, independent processor cores . For example the low-power many-core processors we call Grid-processors – these perform very well on tasks like video encoding, signal processing, cryptography and neural networks. Or Google’s TPU which has 65 thousand 8-bit integer multipliers.
What is core in mobile processor??
Processors are named according to their numbers of complete independent units known as cores.The processor core is the key data-crunching part of a CPU (central processing unit). When you have multiple cores running in parallel, you can run multiple tasks simultaneously with far more efficiency.
Different types of the mobile core processor are :-
1. 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.
2. Quad Core Processors
Quad-core processor is a chip with four independent units that read and execute information and tasks to be done in the central processing unit (CPU). Within the chip, each core operates in conjunction with other circuits such as cache, memory management, and input/output (I/O) ports. The individual cores in a quad-core processor can run multiple instructions at the same time, increasing the overall speed for programs compatible with parallel processing.
3. Hexa Core Processors
Hexa Core Processor is another multi-core processor that is built with six cores. It can handle tasks faster than the dual core and quad core processors. Hexa Core processors have been introduced since 2010. It was launched in Intel Core i7 Hexa-Core processor.
4. Octa Core Processors
The octa core processors are made up of eight (8) independent cores to handle and perform task efficiently. This implies that Octa-core processors can performs double faster than the quad core processor.
5. Deca Core Processors As dual core processors are made up of 2 cores, quad core with 4 cores, hexa core with 6 cores and octa core processors with 8 cores. Deca-core is also made up of 10 complete independent units to handle and perform task very efficiently than other processors. Having deca core processor along with an efficient processor type would really make Gadgets to perform efficiently and super faster than others.
In conclusion,Deca core processor is the latest and new processor. We have only heard about few smartphones having the deca-core processors. Most companies are using Dual Core, Quad Core and Hexa Core processors. Am pretty sure more gadgets with deca-core processors will be welcome towards the beginning of next year. Using Deca core is much better than other core for the performance of the gadgets.
