Гистерезисный триггер для пассивно отказоустойчивых самосинхронных схем

The article analyzes Muller element retaining the completion of the transition process in the self-timed circuits, working on the actual delay elements. Self-timed circuits are considered as one of the most promising options for energy-saving "green" computing, with work on the ultra-low supply voltages and the ability to fix the constant failures. However, this ability allows to build an active failsafe circuit, with this requires an additional control hardware maximum time of completion of the transition process to localize the site of failure and the corresponding reconfiguration (switching to the second channel), which may require a relatively long time. For the implementation of passive failover free of these shortcomings need triple redundancy. At the same time there is a problem completing the analysis of the transition process in the structure with a triple redundancy. It proposed and studied Muller element for redundant structures, retaining the completion of the transition process in at least two of the three channels. Builds a table of transitions of outputs corresponding finite state machine and logic functions are obtained.
