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 for input data increases. In this report, we propose a floating-point multiplier operating based on bit-slice architecture. We design a 2bit bit-slice floating-point multiplier and bit-serial floating-point multiplier at gate level and conpare the performances of them respectively. We design a 2bit bit-slice half-precision floating-point multiplier. The number of junctions and delay time are 50531 and 7849ps. |
