Abstract

The paper introduces a new reusable asynchronous component, called WAITX element, that arbitrates between two requests. In contrast to the traditional mutex, the requests are not required to be persistent, i.e. can be withdrawn at any moment, have hazards or even have high-frequency bursts; e.g. they can be outputs of voltage comparators. It is guaranteed that (i) hazards will never propagate past WAITX; and (ii) when requests are well-behaved, WAITX correctly arbitrates between them. As an additional minor contribution we also design a SAMPLE element on the basis of WAITX; in contrast to previous designs in literature, this SAMPLE is fully speedindependent and unconditionally guarantees that the hazards will not propagate past it.
