Abstract: Techniques for statistics-aware weight quantization are presented. To facilitate reducing the bit precision of weights, for a set of weights, a quantizer management component can estimate a quantization scale value to apply to a weight as a linear or non-linear function of the mean of a square of a weight value of the weight and the mean of an absolute value of the weight value, wherein the quantization scale value is determined to have a smaller quantization error than all, or at least almost all, other quantization errors associated with other quantization scale values. A quantizer component applies the quantization scale value to symmetrically and/or uniformly quantize weights of a layer of the set of weights to generate quantized weights, the weights being quantized using rounding. The respective quantized weights can be used to facilitate training and inference of a deep learning system.

Abstract: An adaptive control method for zero voltage switching belongs to the field of integrated circuit. In the present invention, the difference between the turn-on time of the power tube and the time of the lowest drain voltage of the power tube in the switching cycle is quantified by the reversible counter, and the quantized result is transmitted to the next switching cycle to adjust the turn-on time of the power tube through the final count result of the reversible counter, so that the power tube after being adjusted can be turned on when the drain voltage of the power tube is the lowest, thus reducing the switching loss. The present invention can adaptively turn on the power tube when the drain voltage of the power tube reaches minimum, thus, realizing the zero-voltage switching, reducing the switching loss of the switching power supply, widening the application range.
