Energy minimization techniques over multicore processing system: A review

Energy efficiency and processor performance have become key metrics in the designing of multicore computational systems. Due to breaking down of Moore's law, increasing energy savings without compromising raw performance is considered as a major limiting factor in multicore architecture. Recent technological advances in energy minimizing methods of multicore system substantially meet the contradictory demands of low power, low cost, small area and outstanding performance. This paper aims at ascertaining more competent energy-minimizing techniques for managing energy consumption of multicore processor through investigations. We highlight the necessity of the energy savings techniques and study several novel technologies to focus their pros and cons. This paper is intended to serve the researchers and architects of multicore processors in accumulating ideas about the energy savings techniques and to incorporate it in near future for more effective fabrications.
