Abstract
We conducted the first succe ssful demonstration of
an adiabatic microprocessor based on unshunted Josephson junc-
tion (JJ) devices manufactured using a Nb/AlO
x/Nb superconduc-
tor IC fabrication process. It is a hybrid of RISC and dataflow
architectures operating on 4-b data words. We demonstrate
register file R/W access, ALU execution, hardware stalling, and
program branching performed at 100 kHz under the cryogenic
temperature of 4.2 K. We also successfully demonstrated a high-
speed breakout
