ABSTRACT:
A pattern matching system including a calculating arrangement for calculating a current value of cumulative distances between an input pattern and a reference pattern of a current pattern number at a current input pattern time instant and a current reference pattern time instant by using a dynamic programming algorithm which decreases workload because the current value is selected as a selected distance only when the current value is not greater than a threshold value which is determined at the current input pattern time instant. Work areas or memories are used as a result memory device accessed by a combination of the current input and reference pattern time instants for memorizing or storing the selected distance, the current pattern number, and the current reference pattern time instant, which are for later use in calculating another of the cumulative distances. Preferably, the threshold value should monotonously increase with time. More preferably, two of the work areas are alternatively used.
