Abstract
A generalized event management architecture based upon an analysis of the traditional interprocess communication and synchronization mechanisms is disclosed. An extended semaphore architecture is proposed which combines the properties of Dijkstra's semaphore with that of a trap facility. This model is further developed into a more general architecture capable of handling complex events, structured event condition variables and generalized assignments. The architecture is defined in terms of entity classes, relationship classes and functional primitives. Finally a typical hardware computer system utilizing these concepts is shown and described.
