| 概要 |
Moore’s Law, doubling the number of transistors in a chip every two years, has so far contributed to the evolution of computer systems. Unfortunately, we cannot expect sustainable transistor shrinking... anymore, marking the beginning of the so-called post-Moore era. Therefore, it has become essential to explore emerging devices, and superconductor single-flux-quantum (SFQ) logic that operates in a 4.2- kelvin environment is a promising candidate. Josephson junctions (JJs) are used as switching elements in SFQ logic to compose a superconductor ring (SFQ ring) that can store (or trap) and transfer a single magnetic flux quantum. It fundamentally operates with the voltage pulse-driven nature that makes it possible to achieve extremely low-latency and low-energy JJ switching. This talk shares the history of our SFQ Research, e.g., revisiting microarchitecture and demonstrating over 30 GHz microprocessors, AI accelerator designs, and recently targeting quantum computers. Then, the role of computer architecture for such emerging device computing is discussed.続きを見る
