Basic Components of Computer Processor

• ALU stands for arithmetic logic unit, which help out to execute all arithmetic and logic operations.

• FPU (Floating Point Unit) is also called the “Math coprocessor” that helps to manipulate mathematically calculations.

• Registers store all instructions and data, and it fires operands to ALU and save the output of all operations.

• Cache memory helps to save more time in travelling data from main memory.

Primary Processor Operations

• Fetch – In which, to obtain all instructions from main memory unit (RAM).

• Decode – In this operation, to convert all instructions into understandable ways then other components of CPU are ready to continue further operations, and this entire operations ar performed by decoder.

• Execute – Here, to perform all operations and every components of CPU which are needed to activate to carry out instructions.

• Write-Back – After executing all operations, then its result is moved to write back.

You can Enhance Speed of Processor

The processor’s speed is totally depending on the ability of your CPU. You can boost up the speed of processor as well as increase the processor functionality. If, your CPU is getting unlocked then you are capable to over clock, its means you can increase the frequency of your CPU instead of its standard specifications.

If, you purchase the processor that is locked then you have not chances to increase the processor’s speed.

Types of Processors

Here, we will discuss about different types of processors, which are used in computers. But, these processors are divided into different categories, like as:

• Based on Flynn’s Taxonomy
• Based on Number of Cores
• Based on General Purpose Processor

Processor Types ‘Based on Flynn’s Taxonomy’

Flynn’s taxonomy is a categorization of forms of parallel computer architectures based on the concurrency in processing sequences data, and instructions. From the viewpoint of the assembly language programmer, parallel computers are classified into four classes:

SISD (Single Instruction, Single Data): This is the simplest and most common type of computer architecture. It has only one processor that executes a single instruction stream and a single data stream at a time. It is not a parallel architecture as it does not have multiple processors.

Example: Most traditional desktop and laptop computers are SISD systems.

SIMD (Single Instruction, Multiple Data): This architecture has multiple processing units that execute the same instruction stream on different data streams simultaneously. It is commonly used in multimedia applications such as image and video processing.

Example: Graphics processing units (GPUs) are often SIMD architectures, where a single instruction is applied to multiple data elements simultaneously.

MISD (Multiple Instruction, Single Data): This architecture has multiple processing units that execute different instruction streams on the same data stream simultaneously. It is not commonly used in practice.

Example: Experimental or theoretical architectures rather than mainstream systems.

MIMD (Multiple Instruction streams, Multiple Data streams): This architecture has multiple processing units that execute different instruction streams on different data streams simultaneously. It is the most common type of parallel architecture and is used in multi-core processors, clusters, and supercomputers.

Example: Clusters of interconnected computers, multi-core processors, and distributed computing systems often exhibit MIMD characteristics.

Processor Types ‘Based on Number of Cores’

Processors can be classified based on the number of cores they have. A core is a physical device within a CPU that takes data from a thread and performs processing tasks. Here are the different types of processors based on the number of cores, including:

Single Core Processor: Single Core CPUs were used in the traditional type of computers. Those CPUs were able to perform one operation at once, so they were not comfortable to multi tasking system. These CPUs got degrade the entire performance of computer system while running multiple programs at same time duration.

In Single Core CPU, FIFO (First Come First Serve) model is used, it means that couple of operations goes to CPU for processing according to priority base, and left operations get wait until first operation completed.

Dual Core Processor: Dual Core processor contains two processors, and they are linked with each other like as single IC (Integrated circuit). Every processor consist its own local cache and controller, so they are able to perform different difficult operations in quickly than single core CPU.

There are some examples which are used as dual core processors such as Intel Core Duo, the AMD X2, and the dual-core PowerPC G5.

Multi Core Processor: Multi core processor is designed with using of various processing units means “Cores” on one chip, and every core of processor is able to perform their all tasks. For example, if you are doing multiple activities at a same time like as using WhatsApp and playing games then one core handles WhatsApp activities and other core manage to another works such as game.

Quad Core Processor: Quad core processor is high power CPU, in which four different processors cores are combined into one processor. Every processor is capable to execute and process all instructions own level without taking support to other left processor cores. Quad core processors are able to execute massive instructions at a time without getting waiting pools. Quad core CPU help to enhance the processing power of computer system, but it performance depend on their using computing components.

Octa Core Processor: Octa core processor is designed with using of multiprocessor architecture, and its design produces the higher processing speed. Octa core processor has best ability to perform multi tasking and to boost up efficiency of your CPU. These types of processors are mostly used in your smart phones.

General Purpose Processor

There are different types of general-purpose processors (GPPs) available in the market, each with its own unique features, speeds, and architectures. Here are the different types of general-purpose processors, like as:

Microcontroller: This type of general-purpose processor that is designed to control small devices such as remote controls, toys, and appliances.

Microprocessor:  This processor is used in personal computers, laptops, and servers. It is composed of one or more processing cores that run at a fixed range of clock speed. Used in a variety of devices such as personal computers, servers, and embedded systems.

Embedded Processor: This processor is designed to be embedded in other devices such as smartphones, tablets, and smart watches. It is optimized for low power consumption and high performance.

DSP (Digital Signal Processor): A type of processor is introduced to process digital signals such as audio and video. It is commonly used in smartphones, cameras, telecommunications, image processing and audio equipment.

Media Processor: This processor is designed to handle multimedia tasks such as video encoding and decoding. It is commonly used in gaming consoles, set-top boxes, and smart TVs.

Application-Specific Integrated Circuits (ASICs): ASICs are custom-designed processors for specific applications or tasks. They are not general-purpose but are highly efficient for their intended function. This is used in specialized devices such as network routers, graphic cards, and specific industrial domains.

Multi-Processor Systems: Multi-processor systems have multiple independent processors working together, often sharing memory and other resources. They are used in high-performance computing environments, servers, and certain workstations; and provide scalability and increased processing power.
