The Berkeley Symposium on Energy Efficient Electronic Systems brings together researchers from around the world who are working on breakthrough improvements in energy efficiency for information processing systems. The goal is to foster closer cooperation and collaborations among the researchers working in this domain of technology. Established in 2009, it is a forum for speakers, from academia, industry, and government laboratories, to share their perspectives, and discuss issues and approaches, enabling the attendees to better understand this area from both above and below them on the food chain. We have a grand scope in mind, extending from new low-power nanoelectronic devices, through circuit design, chip-scale architecture, short-range interconnects, long-range interconnect, networks, software, storage systems, servers, data centers and supercomputers. IEEE Electron Device Society became a technical co-sponsor in 2013.
