In order to optimize power consumption, it is important to know where and why power is consumed in a specific system. Power estimation gives a more or less accurate answer for the first question (where?). Knowing where power is consumed allows designers to optimize these specific components. However, the second question (why?) for the reason of power consumption, is more difficult to answer: Ac...

With the ever-growing use of computers and rapid growth in chip fabrication technology, the performance of CPU doubled approximately every 18 months by Moore’s law and CPU clock speed increased exponentially for better performance guarantees. The advancement in IC technology led to the increase in number of chips on a processor which in turn resulted in more power consumption. The basic power c...

Background. Energy awareness in the ICT has become an important issue: ICT is both a key player in energy efficiency, and a power drainer. Focusing on software, recent work suggested the existence of a relationship between power consumption, software configuration and usage patterns in computer systems. Aim. The aim of this work was collecting and analysing power consumption data of a general-p...
