A Simplified State Assignment Method for Asynchronous Sequential Machines,
Abstract
Sequential switching circuits are generally categorized as being either synchronous or asynchronous circuits. Synchronous circuits are those which employ a timing or 'clock' signal to trigger circuit state changes. Asynchronous circuit state changes occur in response to input changes only. Output changes of these circuits are delayed from input changes by simply the switching time of the circuit elements and hence these circuits are capable of the ultimate in sequential circuit speed. Since asynchronous circuits are activated by input changes, unequal circuit path delays could result in undesired internal state transitions which in turn would result in faculty circuit operation. It is, therefore, necessary for asynchronous circuits to be free of such undesired internal state transitions for reliable operation. (Author)
