| Abstract(in English) | Single flux quantum (SFQ) circuits are expected as next-generation circuits. Arithmetic circuits using SFQ circuits have been designed based on bit-serial structure. When the bit width of input data increases, the number of cycles to input data increases. In this report, we propose a multiplier operating at high frequency based on bit-slice architecture. Bit-slice multipliers have feedback loops, and the clock frequency depends on the size of these loops. In the proposed bit-slice multiplier, we minimize the feedback loops. We show that the throughput of the proposed bit-slice multiplier is improved in proportion to bit-slice width, and that the hardware cost of the proposed bit-slice multiplier increases in proportion to bit-slice width. |
