| Abstract(in English) | We report implementation and experimental results of a single-flux-quantum (SFQ) floating-point serial divider developed for a processor with a reconfigurable data-path (RDP), which we have been studying for an accelerator of large-scale computers. The divider is designed based on a hardware algorithm of division by shift and subtract using the signed-digit representation, and implemented with a regularly aligned pipeline structure called a systolic array. As a result, a high-throughput, low-latency SFQ divider is achieved with a small circuit size. A 4-bit divider has been fabricated using the 2.5-kA/cm^2 niobium process technology, and the successful operations up to 19GHz have been demonstrated. |
