We report the successful operation of an energy-efficient 8-bit arithmetic logic unit (ALU)
based on bit-parallel, gate-Ievel-pipelining, and low-voltage rapid single-flux-quantum (LV …

We demonstrate the functioning of a high-throughput, gate-level-pipelined floating-point
adder and multiplier over 50 GHz. The gate-level-pipelined floating-point adder and …

A high-throughput 4 4-bit multiplier was demonstrated using an extremely careful timing
design for low-voltage rapid single-flux-quantum (LV-RSFQ) logic. The design considers the …

In this paper, we successfully demonstrate the 50-GHz operation of a microprocessor
datapath based on single-flux-quantum (SFQ) logic with a gate-level pipeline (GLP) …
