Abstract:A self-timed microarchitecture called KeyRing is presented, and a method for implementing KeyRing circuits compatible with a timing-driven electronic design automation (EDA) flow is discussed. The KeyRing microarchitecture is derived from the AnARM, a low-power self-timed ARM processor based on ad hoc design principles. First, the unorthodox design style and circuit structures are revisited. A theoretical model that can support the design of generic circuits and the elaboration of EDA methods is then presented… Show more
