To meet the growing needs of computing power, communication speed and performance requirements demanded by today's applications, processor clock speed has to be increased. However, increasing clock speed is not viable due to heat dissipation and power consumption constraints. Hence, Instead of trying to increase the clock speed, multi-core processor architectures with the lower frequency can be used. A multi-core processor is a single integrated circuit in which two or more processors have been attached for enhanced performance, reduced power consumption and more efficient simultaneous processing of multiple tasks. Multi-core processors, which have multiple processing units on a single chip, are widely viewed as a way to achieve higher processor performance. Well scheduling of running threads on these processors will result in achieving higher performance.
