Design of an RSFQ microprocessor

We are discussing a general-purpose microprocessor architecture that is suitable for implementation using the Rapid Single-Flux-Quantum (RSFQ) family of logic-memory circuits. While the microprocessor provides a functionally complete RISC instruction set with 16-bit words, a bit-serial self-timed approach makes it simple enough to be fabricated using the current Josephson junction technology. Our plans are to design, fabricate and test a completely operational prototype of this system.<<ETX>>
