Abstract
A method for data quantization is provided. The method includes: receiving data to be quantized; calculating a quantization parameter according to a distribution of the data to be quantized; iteratively calculating an optimal quantization step size according to the quantization parameter and the data to be quantized; and quantizing the data to be quantized according to the optimal quantization step size to obtain quantization data.
