Abstract:
A data processing equipment for classifying inputted data into classes in accordance with peripheral data of the inputted data, and for processing the data for each of the classes, the data processing equipment comprising:storage means for sequentially storing a plurality of data forming the classes;first detection means for sequentially comparing magnitudes of the data stored in the storage means and simultaneously detecting a maximum value and a minimum value of the data by a tournament system;second detection means for detecting a dynamic range as a difference between the maximum value and the minimum value of the data obtained by the first detection means; andoperation means for operating a plurality of thresholds for quantizing the data in accordance with the dynamic range detected by the second detection means, said operation means simultaneously generating a plurality of quantization codes, one for each of said plurality of data in accordance with said plurality of thresholds and generating a class code in accordance with said plurality of quantization codes.
