Abstract (in Japanese) (See Japanese page) 
(in English) We have designed data-path prototypes using the single-flux-quantum (SFQ) circuits fabricated with the AIST 10 kA/cm2 Nb advanced process (ADP) for microprocessors. The microprocessor using SFQ circuits are promising for realization of low-power consumption, high-performance high-end computers. The designed data-paths are composed of 2 registers placed in parallel and an arithmetic logic unit (ALU). The outputs of the registers are connected to the inputs of the ALU via a switch circuit, and the output of the ALU is connected to one of the inputs of the registers via another switch circuit. In this study, we have designed the data-paths based on the cell-based design technique, using the conventional cell library and low-power cell library with 1/10 power consumption, and confirmed the partial operations.
