A novel two-phase RZ delay-insensitive asynchronous handshaking protocol for on-chip communication has been developed along with an efficient and robust dual-rail circuit implementation (Transmitter/Receiver). Performance was verified using SPICE simulations with a 0.13 μm, 1.2 V technology and compared to that of the best-in-class asynchronous transceivers in terms of forward and backward latencies, throughput, energy per bit transfer and design complexity. Results demonstrate the superior overall performance of the new transceiver.
