Abstract :
This paper presents a generalization of a previously proposed asynchronous wave-pipeline architecture. Four-phase and two-phase communication units supporting more than one wave in the logic are proposed. General feedback structures are then outlined. Simulations from a 16-bit add-and-shift ring demonstrate their feasibility. The same architecture is applicable for both datapath and control enabling the realization of complete high-throughput asynchronous systems
