What is the full form of CPU?
The “brain” of a computer or other computing equipment is frequently referred to as the Central Processing Unit (CPU). It is an essential part that is in charge of carrying out the computations and executing the instructions that power a computer system’s overall operation.
Three key tasks are carried out by the CPU
1. Fetch:
The CPU fetches instructions from the RAM, or random access memory, of the computer. The Instruction Cache is a specialised cache memory where the fetched instructions are temporarily stored.
2. Decode:
The CPU decodes the instructions once they have been fetched in order to find out their meaning and the steps necessary for carrying them out. In order for the CPU to process the instructions, they must be divided into smaller pieces.
3. Execute:
The CPU carries out the required computations or operations to carry out the instructions after they have been decoded. Also, tasks including arithmetic operations, logical comparisons, data transfer, and control flow instructions can be included in this.
The following essential parts make up the CPU
1. Control Unit (CU):
The Control Unit is in charge of organising and controlling how orders are carried out. Also, it regulates the data flow between various CPU components and other hardware elements.
2. Arithmetic Logical Unit (ALU):
The ALU performs the addition, subtraction, multiplication, and division operations in addition to the logical operations AND, OR, and NOT needed for computations and decision-making.
3. Registers:
The CPU uses registers, which are compact, high-speed memory modules, to store and manipulate data while processing. They also store information, instructions, and early findings.
4. Cache Memory:
Located inside the CPU, cache memory is a tiny yet incredibly quick memory component. In contrast to retrieving data from the main memory, it allows for speedier access by storing frequently used data and instructions.
5. Clock Signal:
A clock signal that synchronises and also controls the timing of various processes powers the CPU. Hence, the speed at which instructions are carried out and data is processed is determined by the clock signal.
Types of CPU
The different types of CPUs are:
1. Desktop CPUs:
These are made for workstations and also for personal PCs. Also, they are available in many families, including AMD Ryzen series, Intel Core i3, i5, i7, and i9. Generally speaking, they are optimised for a trade-off between performance and power consumption.
2. CPUs for servers:
These CPUs are made for server systems and data centres, where multitasking and high-performance computing are essential. So, server settings frequently use CPUs like AMD EPYC and Intel Xeon.
3. Mobile CPUs:
These CPUs are made especially for portable electronics like laptops, tablets, and smartphones. So, for extended battery life, their power efficiency has been optimised. Mobile CPUs from Qualcomm Snapdragon, Apple A-series, and Intel Core are some examples.
4. Embedded CPUs:
These CPUs are a part of embedded systems, which include industrial machinery, automotive electronics, and Internet of Things (IoT) gadgets. Moreover, they are frequently made for unique applications that need minimal power consumption.
5. Workstation CPUs:
These CPUs are intended for demanding applications like video editing, scientific simulations, and also 3D modelling. Hence, Compared to desktop CPUs, they provide more cores, greater cache memory, and sophisticated functionality.
6. Mainframe CPUs:
Organisations employ mainframe computers, which are massive, high-performance systems used for important applications. They also make use of specialised CPUs built for high availability, scalability, and dependability.
7. CPUs for supercomputers:
Supercomputers are made for handling enormous quantities of data and also performing complicated calculations. To attain high-performance computing capabilities, they employ specialised CPUs, moreover sometimes with many processors or cores.
