The energy efficiency of electronic devices, particularly computers, is an important research topic across the electrical engineering and computer science sides of the department. One important aim is to dramatically decrease the power use of proliferating computer servers and data centers.
Progress is required across all levels of electronic systems, from engineering materials for devices to circuit optimization, redesigns of circuit architectures, governing software, and computing paradigms. It is predicted that continued research in energy-aware design has the potential to reduce energy consumption by several orders of magnitude. As an example, to implement a logic function using engineered hardware requires up to 1000 times less energy than implementation on a microprocessor running software. MIT is actively engaged in many system-level efforts to optimize energy efficiency, with recent examples such as development of leading ultra-low-voltage digital circuits, the use of III-V devices for computational logic, the use of photonics for low-power intra- and inter-chip communications, the invention of ground-breaking amplifier-less analog circuits, and low-power digitally-assisted radio-frequency circuits. Recently demonstrated techniques show the potential to reduce power dissipation by more than an order of magnitude by integrating research across disciplines.
