The Swiss Federal Institute of Technology (ETH Zurich) is a science and technology university with an outstanding research record. ETH Zurich is the study, research and work place of 18,000 people from 80 nations. About 350 professors in 15 departments teach mainly in the engineering sciences and architecture, system-oriented sciences, mathematics and natural sciences areas and carry out research that is highly values worldwide.
The Department of Information Technology and Electrical Engineering (D-ITET) includes a dozen research laboratories with activities in the broad area of electrical engineering, ranging from integrated circuits to computer networks, from wireless communications to signal processing, and from control theory to power electronics. The faculty of D-ITET consists of about 30 professors that supervise over 300 Ph.D. students. The department is firmly committed to both basic and applied research.
The Digital Circuits and Systems group led by Prof. Benini focuses on architecture, hardware and software design of energy-efficient computing systems. The group is involved in a number of EU funded research projects (e.g. HERCULES, PHIDIAS, PRO3D, VIRTICAL in the ICT Cooperation program, SCALOPES, SMECY in the ARTEMIS JTI, MODERN, END In the ENIAC JTI), including the ERC AdG-MULTITHERMAN project focusing on sustainable computing systems. The group is also very active in industrial cooperation and technology transfer with major companies in the computing field, such as Intel, NXP, ST Microelectronics and Samsung Electronics.
Contribution to OPRECOMP
The goal of OPRECOMP is to develop computation systems that perform over a very large operation range and achieve an energy efficiency that is simply unattainable with traditional digital design paradigms. Unless there is a major shift in the way systems are designed, performance of future systems will be at the mercy of technological developments forecast by Moore’s Law, which slowly and surely is reaching physical limits.
With this project we want to rethink the way we do computations and take inspiration from nature, where multiple very simple organisms with extremely limited capabilities come together to produce impressive feats of calculations. OPRECOMP will rely on small, fast and efficient systems to perform the bulk of the calculations with various degrees of accuracy. Unlike traditional approximate computing systems, that limit the accuracy of specific calculation units, in this project we plan to free data in the intermediate stages of the calculation from accuracy constraints not only during computation, but also while it is stored and transferred within the system without affecting the quality and validity of the final result.
Classical digital computing systems have always been optimized under the assumption that all calculations are accurate. Once this constraint is lifted, many interesting opportunities appear that allow to trade-off the performance with the accuracy. ETH Zürich will develop computation nodes that will exploit this trade-off and allow data to be processed, stored and transmitted at different accuracy levels while still maintaining accurate control flow of the system and enabling the system to precisely bound and control the accuracy of the final result.
