• API function: Computes the mean value and the reciprocal of the standard deviation for the input data of a single card.

• Formulas:

  Mean value:

  $$\bar{x} = \frac{\sum_{i=1}^{n} x_i}{n}$$

  Reciprocal of standard deviation:

  $$\frac{1}\sigma = \frac{1}{\sqrt{\frac{1}{n}\sum_{i=1}^{n}(x_i- \bar{x})^2 + eps}}$$

Each operator is divided into two phases (../common/Two-Phase Interface.md). You must call the aclnnBatchNormStatsGetWorkspaceSize API to obtain the input parameters, calculate the required workspace size based on the workflow, and then call the aclnnBatchNormStats API to perform the calculation.
