Abstract: A data processing method is provided, which can be applied to calculating a histogram of a preset data sequence. Each piece of data in the preset data sequence comprises an exponential part and a mantissa part. The method comprises: performing normalization processing on the preset data sequence to obtain a first index and a first mantissa of each data; according to the first index and the first mantissa of each data, generating a register address; and according to the register address, adjusting a numerical value in the corresponding register. The data processing method provided by the disclosure can be used in the process of statistical sorting of fixed point non-negative real number data such as ADC sampling data, floating point non-negative real number data such as two-dimensional FFT power data, and other types of data.
