DescriptionCurrently, data center power consumption accounts for over 1% of the world’s energy usage. With this figure expected to increase significantly over the next decade, it is imperative to identify new ways to reduce computing power consumption. With recent advancements in cryogenic cooling technology, it is timely to explore the applicability of cryogenic computing technologies in solving the data center energy problem. Additionally, such cryogenic systems could also have applications in quantum computing. Such quantum computers offer the promise to provide an exponential speedup for certain compute applications, which are pervasive across multiple segments of the economy. Low-temperature CMOS operation results in higher threshold voltage and improved subthreshold slope, leading to low leakage power consumption. Despite these advantages, cryogenic CMOS operations need to operate at moderately higher supply voltage due to higher threshold voltage for achieving the same operating frequency. Higher supply voltage leads to higher switching energy dissipation resulting in increased cooling cost. Hence, there is a critical need to investigate the usefulness of cryogenic computing across various bottom-up levels of abstractions (process, device, circuits, EDA) and from top-down application-level perspectives (such as quantum computing, high-performance computing CMOS booster). This panel brings together leading researchers in this field to provide their perspective on this timely and important topic which would benefit the entire DAC community.
