Power Management Systems or PMS are the systems which reduce the power consumption of any asset in use. Many research institutes and universities have been doing commendable work in this field worldwide to widen the scope of PMS. One such system recently explored by University of Washington extends the PMS’s scope to computers.
The system known as EnergJ system (named on the renowned Java operating system) can cut power consumption by up to 90 percent. If the claims made by the sources are right, it will be a landmark step in the history of Green Computing.
EnergJ system provides the minimum required amount of power to the regions of chip that are performing the processes and require comparatively less accuracy. The same principle will be applied to software in addition to chips. In programs where exact figures are not important or can be rounded off, this system can work well and expects to enhance the productivity of the subject system.
According to the University sources, it has already cut power consumption up to 50 percent in simulation and is expected to go up to 90 percent in actual use. Simulations have proved that computers running with EnergJ-controlled hardware have an average power-savings of 20 to 25 percent, and that increased to 50 percent during one program. By applying this system to softwares also, it is estimated that an additional 30 to 50 percent power savings could be realized. UW hopes to unveil its open-source code for general use in future.
