Abstract:
1. A parallel operation histogramming device comprising: a number N processors capable of parallel operation; a number M counters which output respective operation results for each parallel operation by the N processors, the number M also being the number of histogram bins; a histogram counter circuit which accumulates and stores, for each counter, the outputs of the M counters; and N signal generation circuits which generate M types of classification signals for indicating which of the M types of histogram values the respective operation results belong to, wherein: the M counters receive as input and count, for each type, classification signals output from the N signal generation circuits so as to acquire, for each parallel operation by the N processors, a number of pieces of data for each of M types of histogram values to which the respective operation results belong; and each of the M counters is configured to receive input from all N signal generation circuits.
