A MODULAR REALIZATION OF SYMMETRIC SEQUENTIAL MACHINES,
Abstract
A class of sequential machines which display certain symmetries in their state diagrams is investigated with emphasis on the cascadeparallel interconnection of elementary, rather than arbitrarily complex, asynchronous sequential machines. It is shown that additional feedback around a (Huffman model) machine may be used to eliminate certain states of the state diagram. This feedback is restricted only in that the delay through the feedback path must be greater than the delay associated with the secondary variables around which the feedback is made. Then it is shown that interconnections of elementary modules yield machines that have symmetric state diagrams, and that feedback may be used to create certain asymmetries. (Author)
