/Nb superconductor IC fabrication process. It is a hybrid of RISC and dataflow architectures operating on 4b data words. We demonstrate register file R/W access, ALU execution, and program branching performed at 100kHz under the cryogenic temperature of 4.2K. We also successfully demonstrated a high-speed chip of the microprocessor execution units up to 2.5GHz. We use a logic primitive called the adiabatic quantum-flux-parametron (AQFP) which has a switching energy of 1.4zJ when driven by a 4-phase 5GHz ac-clock at 4.2K. |
