DML_ELEMENT_WISE_BIT_SHIFT_LEFT_OPERATOR_DESC structure (directml.h)

Performs a logical left shift of each element of ATensor by a number of bits given by the corresponding element of BTensor, placing the result into the corresponding element of OutputTensor.

f(a, b) = (a << b)

The bitwise operation is applied to tensor data in its native encoding. Therefore, the tensor data type is ignored except for determining the width of each element.

This operator supports in-place execution, meaning that OutputTensor is permitted to alias one of the input tensors during binding.

Syntax

struct DML_ELEMENT_WISE_BIT_SHIFT_LEFT_OPERATOR_DESC {
  const DML_TENSOR_DESC *ATensor;
  const DML_TENSOR_DESC *BTensor;
  const DML_TENSOR_DESC *OutputTensor;
};

Members

ATensor

Type: const DML_TENSOR_DESC*

A tensor containing the left-hand side inputs.

BTensor

Type: const DML_TENSOR_DESC*

A tensor containing the right-hand side inputs.

OutputTensor

Type: const DML_TENSOR_DESC*

The output tensor to write the results to.

Availability

This operator was introduced in DML_FEATURE_LEVEL_2_1.

Tensor constraints

ATensor, BTensor, and OutputTensor must have the same DataType, DimensionCount, and Sizes.
