In this paper the real time implementation of a dynamic time warping based isolated word recognizer on the general purpose, cellular Array Processor (CAP) chip ACIIM will be described. In this implementation a single CAP performs both the preprocessing and the DTW computations. The front-end is based on a parallel filter banck. The DTW computation proceeds on a diagonal basis, where each diagonal is computed by the array of 16 processors contained in the CAP. The time needed for a diagonal computation is 10.5 us. With a pipelined structure in the reference templates, more than 800 DTW computations can be computed in 600 ms assuming an average word duration of 0.8 seconds.
