The thesis describes a study which aimed to devise a means of classifying the complex digital components (e.g. microprocessors) available now and in the future. The motivation was to assist designers to understand the options open to them in implementing a digital system. The outcome of the study is a method of analysing components into their active and passive parts - termed 'agent' and 'data graph' respectively. These elements may then be classified using a scheme developed during the study. The conclusions to be drawn from the work are that it is possible to devise a classification method for complex digital components; but that the method may need to be so abstract that it is of limited use to designers at a practical level. The thesis attempts first to show the relationship between the description iof a digital system, and its implementation. Two distinct approaches to system description are identified and compared: the 'control driven' approach, and the 'data driven' approach. The latter is adopted for the remainder of the thesis. Implementation of a data-driven system is shown to require a passive 'data graph', in which are embedded a number of active 'agents', one for each concurrent process in the system. Classification schemes for agents and data graphs are presented, based on an analysis of real components and systems. Two appendices are provided: one is a reproduction of an article describing the classification of certain features of microprocessors; the other analyses a real system by means of the methods proposed in the study.
