Abstract :
The basic principles behind Josephson digital circuits are reviewed, and the possibility of multivalued logic operation is discussed. Four high-speed Josephson LSIs developed by the authors are described. They are a 4-b microprocessor, a 4-b processor, an 8-b digital signal processor, and 4-kb memory. Their specifications and performances are summarized, and their characteristics are briefly discussed. Preliminary experimental results with a prototype Josephson computer are reported
