| Abstract(in English) | Single Flux Quantum (SFQ) circuits operate at high-speed with low-power consumption. A Large-Scale Reconfigurable Data Path (LSRDP) is proposed as an accelerator of a high-performance computer. The previously proposed floating-point arithmetic units (FPUs) for SFQ-LSRDP are based on the bit-serial architecture. For accomplishing an operation on long-bit data, bit-serial FPUs take a lot of clock cycles, and their throughputs are low. In this report, we propose bit-slice floating-point adders (FPAs). For a k-bit bit-slice FPA, we employ a radix-2^k floating-point number format. Compared to the bit-serial FPA, a k-bit bit-slice FPA takes about 1/k number clock cycles with slightly larger hardware, and its throughput is expected to be k times higher. |
