The asynchronous rapid single-flux quantum electronics – a promising alternative for the development of high-performance digital circuits

Abstract. In this paper, we investigate the application of the asynchronous logic approach for the realization of ultra high-speed digital electronics with high complexity. We evaluate the possible physical, technological, and schematical origins of restrictions limiting such an application, and propose solutions for their overcoming. Although our considerations are based on the rapid single-flux quantum technique, the conclusions derived can be generalized about any type of digital information coding.

Ic Technology

Rapid Single-Flux-Quantum (RSFQ) logic is a superconductor IC technology that, with only a modest number of researchers worldwide, has produced some of the world's highest performance digital and mixed-signal circuits. This achievement is due, in part, to a constellation of characteristics that manifest themselves at the circuit level – namely, high-speed digital logic at low-power, ideal interconnects, quantum accuracy, scalability, and simplicity of fabrication. A necessary key to translating these advantages to the system-level involves understanding the I/O, synchronization, and packaging issues associated with a cryogenic technology. The objective of this paper is to review the status of current RSFQ circuit-level infrastructure components and their potential impact on system-level applications.

Switch Circuit

Internet traffic loads are increasing. Sustaining packet switching throughput of a core node will be difficult. A major reason for this is power consumption and packaging volume. As long as we use only current semiconductor technology, the switching capacity will be limited. Rapid single flux quantum (RSFQ) superconducting technology can overcome such difficulties because of high-speed operation and low-power consumption characteristics. A superconducting wiring also enables high-speed inter-chip communication. We report on progress on packet switch circuit implementation and cryo-cooled packaging for a RSFQ packet switch system. In addition, we discuss a possible packet switch architecture over 100 Tbps that uses RSFQ technology.
