Power reduction techniques for microprocessor systems
Static energy reduction techniques for microprocessor
previous efforts at power reduction have focused on dynamic power sources because static power due to leakage current has been a small fraction of the total power dissipated by a chip. However, as transistor threshold voltages are reduced, subthreshold leakage current increases dramatically. Fig. 1 shows estimated static power consumption due

Power Reduction Techniques For Microprocessor Systems
"Power consumption is a major factor that limits the performance of computer systems." Some of this power is used in a very small area which would mean a high power density. As you can see from the chart that modern processor are reaching power density level that are comparable to that found in a nuclear reactor. As chips have gotten more powerful, as to has their heat sinks and
Power Management of Multicore Systems | SpringerLink
Power management in electronic systems is primarily targeted toward two purposes. First is to minimize heat dissipation in order to improve the system''s usability (for handheld devices and wearables), reliability (for safety- and mission-critical systems), etc. Secondly, the power management methods may target the minimization of the system''s energy consumption.
