Abstract
A Single-Flux-Quantum (SFQ) 4-bit throughput-oriented processor has successfully been demonstrated at up to 32 GHz with the measured power consumption of 6.5 mW. This is the first implementation of the gate-level-pipelined processor, and it achieves 2.5 Tera-Operations Per Watt (TOPS/W) by circuit and architectural optimizations.
