Multireader and multiwriter asynchronous communication mechanisms

Abstract

Mechanisms are known which allow asynchronous communication between a single writer and a single reader with no mutual timing constraints. Multireader and multiwriter forms can be constructed by simple replication of the one-reader–one-writer mechanisms. The paper gives a more integrated solution for a multireader mechanism which offers some economy over replication. The additional control logic required for a multiwriter solution is also derived. These solutions can be combined to give generalised multireader–multiwriter mechanisms.
