Development of High-speed and Low-power Microprocessors using Superconductive Circuits

Abstract

Superconductive single flux quantum (SFQ) circuits, which perform their circuit operations by controlling propagations of flux quanta in connected superconducting rings, can operate at the frequency of several tens GHz with ultra low power dissipation. The SFQ circuit is thought to be an attractive candidate for fundamental elements of future high-end information processing systems. This paper reports the development of SFQ microprocessors for high-end computation systems.
