  4. Part 1 Introduction • Multi-core processors represent a major evolution in computing technology. • They are several mostly independent cores which work together in parallel • This important development is coming at a time when businesses and consumers are require it • benefits offered by these processors due to the exponential growth of digital data and the • globalization of the Internet. • performance and productivity benefits beyond the capabilities of today’s single-core processors.

  5. History • The first commercial dual core processor was IBM's Power 4 processor for it's RISC servers in 2001. • The first dual core processor for home use was Intel's Pentium Processor Extreme Edition 840, released in early April 2005. • Less than two weeks later AMD brought their Opteron 800 Series and Athlon 64 X2 processors to market.

  6. Why multi-core pocessor-? Once upon a time, when human realized that in a normal atmosphere ,it is not possible to increase the CPU’s clock speed after above standard level (generally at a frequency about 4Ghz the CPU would get too hot and take a lot of electricity). Because of too much heat generated by CPU both Intel & AMD faced problem. High clock speed means high heat & resulted boom the CPU.

  7. Faster processing is the basic reason ,so that’s why technology shifted towards the Multicore processor rather than increase the clock frequency. It was decided to put more than one processor on a single die. That is what we call two core or dual core .

  8. What do you mean by Multi core? • A multi-core microprocessor is one which combines two or more independent processors into a single package, often a single integrated circuit. • A Multi-core computing • A dual-core device contains only two independent microprocessors.

  9. If multi means two or more, what types are there? A dual-core processor contains two cores. A quad-core processor contains four cores. A processor with all cores on a single die is called a monolithic processor.

  18. Single Core vs. Multicore

  19. What is a 64 bit chip? • A 64-bit processor means that it can handle 64 bits of data at one time. • A 64-bit processor can handle more intensive programs than a 32-bit. • The 64-bit processor also supports more memory than a 32-bit processor. 32-bit CPUs can generally handle up to 4GB of memory, with the ability to process 2GB of memory at a time while a 64-bit system can utilize more significantly

  20. Performance Analysis

  21. Part 3 Advantages • Multi-tasking productivity •  it will work faster for certain programs • PC security • Cool and quiet • The signals between different CPUs travel shorter distances, therefore they degrade less • More features can be added to the computer

  22. Disadvantages • They do not work at twice the speed as a normal processor. They get only 60-80% more speed. • The speed that the computer works at depends on what the user is doing with it. • They cost more than single core processors. • They are more difficult to manage thermally than lower-density single-core processors.

  23. Applications • Video editing • Encoding . • 3D gaming. • Powerful graphics solution • Optimized productivity titles, such as AVG's virus-scanning software. • The full effect and the advantage of having a multi-core processor, when it is used together with a multithreading operating .

  24. Multicore Challenges • Having multiple cores on a single chip gives some challenges . • Power and temperature management • Memory/cache coherence is another challenge • And finally, using a multicore processor to its full potential is another issue

  25. Future aspect • Next-generation software applications will • require the performance capacity provided by • multi-core processors. Software destined to • break barriers in the user experience, like as • Voice recognition • Artificial intelligence (AI) • That will be only possible by multi-core processors

  26. Part 4 Conclusion In the next years the trend will go to multi-core processors more and more. The main reason is that they are faster than single-core processors and they can be still improved., but added interesting new problems. But in the future there will be still some applications for single-core processors because not every system needs a fast processor.
