Abstract
A logic circuit comprises: an event generator for detecting a variation in data output from a signal source to generate an event which indicates the variation of the data; a plurality of propagation elements for propagating the event in a chained fashion; and a plurality of evaluation elements for evaluating data received at a first stage from the signal source to propagate a result of the evaluation in a chained fashion. When receiving the event, each of the plurality of evaluation elements evaluates the data input to the evaluation element.
