A new data encoding scheme using multi-valued logic for an asynchronous handshake protocol

Conventional delay-insensitive (DI) data encoding mechanisms, such as dual-rail and 1-of-4 data encoding, suffer from increased wire costs and high power dissipation since 2N+1 physical wires are needed to transmit N-bit data. In this paper, a new data encoding scheme that uses multiple-valued logic (MVL) is proposed to reduce the number of wires needed, and this scheme is simulated and verified using Spice modeling.
