Performance analysis of multicore processors using multi-scaling techniques

Integrating more cores per chip enables programs to run simultaneously, and easily switch from one program another, the system performance will be improved significantly. However, this current trend of central processing unit (CPU) cannot maintained since budget power has not risen while consumption core slowly reduced. Generally, processor’s maximum is proportional product number their frequency they are running at. usually limited by constraints power. In study, first, voltage/frequency adjustment been analyzed for several improve within constraint Second, impact dynamically scaling summarized additional improvements active applications. Finally, it verified that simultaneously can a higher dissipation or under constraints. The analysis obtained in real-time simulation on Linux operating using GEM5 simulator. Results indicated improvement was attained at 59.98%, 33.33%, 66.65% three scenarios, respectively.
