SEARCH FOR EXCELLENCE & PERFORMANCE-MULTICORE PROCESSORS

ABSTRACT. New trend for achieving high performance in processors history as well as evolutionary change in the world of IT has revolutionized the concept of speed and performance in industry.The best way to enhance performance is the way to add multiple cores. To take full advantage of Multi-core processors require some means of dividing work among the cores. It’s up to industry to overcome the problem of programming and hardware to take the full advantage of multi cores. With the passage of time, Pc’s have become rifer and a large number of applications have been designed for the PC’s and end-users and application programmers need more faster and more powerful system capable of performing by trillions of instruction with low price and high performance. A number of factors have achieved speed by increasing clock speed, adding multiple cores but on the same chip. But here the time is not on end all the manufacturers moves upon to use multiple cores. Multi core simulations helped to understand the communication overhead. This paper shows how far industry has progressed and evaluates some challenges that industry faces with multi-core processors. The focus of this paper is on defining a relationship between performance and power level of multicore processors and single core processors by defining complete history of processors and what the reason behind the innovation of multi-cores was? How they help to achieve highest performance
