Abstract(in English) | SFQ/CMOS hybrid system, which is a hybridized system of SFQ circuits and CMOS memories, has been proposed as a large-scale memory solution for single-flux-quantum (SFQ) circuits. In this study, we designed and tested an SFQ microprocessor with an SFQ/CMOS hybrid memory, which we had implemented so far, for the demonstration of the SFQ/CMOS hybrid system. We adopted a one-instruction-set-computer architecture, SUBNEG. The system was designed and implemented with superconducting interface circuits by using the Josephson integrated circuit process, AIST-ADP2. A 64-kb SFQ/CMOS hybrid memory was combined with the SFQ microprocessor, where SFQ processor can access to a 16×4-bit memory space. In the measurement, the correct operation between the SFQ processor and the CMOS memory was obtained, and a simple integer sorting program was demonstrated. |
