Multi-core processors combine two or more independent processors into a single integrated circuit to improve performance. They emerged as a solution to physical limitations threatening single-core processor improvements. By having multiple cores work in parallel, multi-core processors can achieve higher speeds than single-core processors and help address overheating issues. However, fully utilizing multiple cores requires changes to programming methods and not all software is optimized for multi-core systems.

PowerPoint Presentation on the popular topic Multi Core Processors,History of multi core processors, comparison between single core and multi core processors, advantages and disadvantages of multi core processors.
A multi-core processor is a single computing component with two or more independent actual processing units (called "cores"), which are units that read and execute program instructions. The instructions are ordinary CPU instructions (such as add, move data, and branch), but the multiple cores can run multiple instructions at the same time, increasing overall speed for programs amenable to parallel computing. Manufacturers typically integrate the cores onto a single integrated circuit die (known as a chip multiprocessor or CMP), or onto multiple dies in a single chip package.

Multiprocessor system is an interconnection of two or more CPUs with memory and input-output equipment
The components that forms multiprocessor are CPUs IOPs connected to input –output devices , and memory unit that may be partitioned into a number of separate modules.
Multiprocessor are classified as multiple instruction stream, multiple data stream (MIMD) system.

Parallel computing is a type of computation in which many calculations or the execution of processes are carried out simultaneously. Large problems can often be divided into smaller ones, which can then be solved at the same time. There are several different forms of parallel computing: bit-level, instruction-level, data, and task parallelism. Parallelism has been employed for many years, mainly in high-performance computing, but interest in it has grown lately due to the physical constraints preventing frequency scaling. As power consumption (and consequently heat generation) by computers has become a concern in recent years, parallel computing has become the dominant paradigm in computer architecture, mainly in the form of multi-core processors.

IT Engineer are high-level IT personnel who design, install, and maintain a company's computer systems. They are responsible for testing, configuring, and troubleshooting hardware, software, and networking systems to meet the needs of the employer.
A processor is multipurpose, programmable device that read binary instructions from memory, accepts binary data as input and processes data according to that instruction, and provides results as output. It can be viewed as data processing unit of a computer. It has computing and decision-making capability
I have introduced developments in multi-core computers along with their architectural developments. Also, I have explained about high performance computing, where these are used. At the end, openMP is introduced with many ready to run parallel programs.
A dual-core processor is a CPU with two processors or "execution cores" in the same integrated circuit. Each processor has its own cache and controller, which enables it to function as efficiently as a single processor. However, because the two processors are linked together, they can perform operations up to twice as fast as a single processor can.
4. So what are multi-core processors? A multi-core processor is one which combines two or more independent processors into a single package, often a single integrated circuit.
5. An independent processor = a Core Multiple cores are made to work in parallel to achieve better performance So.. More cores = Better performance
6. Background Increase in the no of transistors Moore’s law Every 18 months component density doubles.
7. Background A system used methods like Concurrency and others to achieve speedups. Some physical limitations were threatening to come in the way of processor performance improvement.
8. Why so much Hype about Multi-core technology?!? It all started 7 years ago, when chip makers realized that single core processor was reaching its threshold in performance. Overheating became a critical issue. Dependence on the processor frequency and no of transistors in the chip for performance improvement.
10. It was in this deadlock kind of situation, the concept of ‘multiple cores in a single chip’ emerged. A chip with two cores, working in parallel could accomplish twice as much as a chip with one core. Since then the performance factor has been going up significantly with the increase of no of cores..
11. How has this helped us? Performance upgrade, which is obvious. If each core is working at say 2.5GHz, then a dual core processor can work at speeds from 4 – 4.5GHz, which is never achievable using a single core processor. Lower power usage and Overheating issues. Multi-core processors gave rise to Multi-core programming which is said to be an important leap in software development than that of OO.
13. CPU State CPU State Execution unit Execution unit Cache Cache A simple multi-core architecture consists of 2 independent working processors. Each core or CPU consists of its own set of Execution unit and Cache. There are other multi-core architectures. Multi-core with shared memory Multi-core with Hyper Threading technology
14. Some Facts and terminologies Intel and AMD ( Advanced Micro Devices ) are the 2 giants in desktop/laptop processor manufacturers.
15. A Dual core processor is a simplest multi-core processor running with 2 independent cores. AMD Phenom II X2 Intel Core Duo Similarly there are Quad core, Hexa core are processors with 4 and 6 cores. AMD Phenom has both its 4 and 6 core versions Intel has the new Core line processors. Core i5 has a quad /dual core variant. Intel Core i7 Extreme Edition 980X is a 6 core processor.
16. Recent updates Intel Xeon ‘V8’ was launched recently which has 2 Quad core processors making it a 8 core processor.
17. Intel’s Core i7 Extreme Edition 980X and AMD’’s Phenom II X6 1090T Black Edition are the most powerful Desktop CPU’s available right now. Both are 6 core processors but AMD’s processor is lot cheaper compared to that of Intel.
18. Atom – THE Smallest processor Intel launched a Dual core version of the its Atom processor for netbooks. Each core being 1.5GHz, the processor has a decent impact.
19. Downside of Multi-Cores All the programs might not run efficiently in a multi-core system. Sometimes it even might result in lose of performance. Parallelizing the programs is not a simple task. Speed of the system depends on what the user is doing with it. Multi-core processors are very expensive.
20. CONCLUSION A multi-core processor has been the trend from past 5-6 years and will continue to be for next few years too. But just increasing the no of cores with not proper support from other hardware and software side will not work. Intel Atom processor has tremendous potential.
